Description
Happens independently with both smuxi-server and smuxi-frontend-gnome and doesn't fix itself until I restart the computer. It seems only to happen on process startup; processes that have been running for a while don't spontaneously get it.
Have attached strace and Mono trace and aptitude installed packages and their versions.

- Status changed from New to Feedback
So they hang on startup and nothing happens? Please run the following from the same terminal that you use to start smuxi-server or smuxi-frontend-gnome and paste the output:
grep SigBlk /proc/self/statusUpdated by Infinity Zero 4026 days ago
Currently server is running OK, frontend hangs every time:

gnome-session quirks¶
I logout with xfce4-terminal open, a child of gnome-panel; then log back in.
Sometimes xfce4-terminal doesn't show up. but when it does, it always has a different non-0 SigBlk, even if the previous instance had 0 SigBlk. It has also detached from gnome-panel, and is a direct child of gnome-session.
$ ./get-sigblk $(pidof gnome-session) # sigblk of 13462 and direct children # pid ppid sigblk args 13462 13140 SigBlk: 0000000000000000 gnome-session --session gnome-fallback 13712 13462 SigBlk: 00000000023262a0 gnome-panel --sm-client-id 106ab6feb6ee9ae63138444076344777600000208680000 13795 13462 SigBlk: 00007ffe190ade30 xfce4-terminal --geometry=267x77 --display :0.0 --role=xfce4-terminal-1384441236-1420310038 --show-menubar --show-borders --hide-toolbar --working-directory /home/infinity0 --sm-client-id 10409af4e88eadb3fb138444123671792400000045930038 [other info redacted]
When I close xfce4-terminal and re-launch it from gnome-panel, xfce4-terminal always has non-0 SigBlk. However, when I kill gnome-panel (forcing it to be restarted), then sometimes it works - see below.
gnome-panel quirks¶
I kill gnome-panel, sometimes gnome crashes with "you must log out" message so I need to re-log.
More often than not, it restarts correctly. I then close all instances of xfce4-terminal (re-launching re-uses the process), and also re-launch gedit and smuxi-frontend-gnome.
- gedit always has 0 SigBlk
- smuxi-frontend-gnome always has the same non-0 SigBlk as gnome-panel
- xfce4-terminal sometimes has non-0 SigBlk
The SigBlk behaviour (either 0 or non-0) of the children remain the same, until I kill gnome-panel again.
$ ./get-sigblk $(pidof gnome-panel) # sigblk of 15103 and direct children # pid ppid sigblk args 15103 7483 SigBlk: 00000000027902c0 gnome-panel 15226 15103 SigBlk: 00000000027902c0 mono --debug /usr/lib/smuxi/smuxi-frontend-gnome.exe 15573 15103 SigBlk: 00007ffe17e94c80 xfce4-terminal --geometry=120x40+0-0 16137 15103 SigBlk: 0000000000000000 gedit
$ ./get-sigblk $(pidof gnome-panel) # sigblk of 23068 and direct children # pid ppid sigblk args 23068 21802 SigBlk: 00007ffe0fd98090 gnome-panel 23159 23068 SigBlk: 0000000000000000 xfce4-terminal --geometry=120x40+0-0 31856 23068 SigBlk: 00007ffa0fd98090 mono --debug /usr/lib/smuxi/smuxi-frontend-gnome.exe 31864 23068 SigBlk: 0000000000000000 gedit
"Sometimes" seems to follow this pattern:
- ("good") if SigBlk of gnome-panel starts 00007ff, xfce4-terminal will have 0 SigBlk
- ("bad") if SigBlk of gnome-panel starts 0000000, xfce4-terminal will have SigBlk starting with 00007ff
I've tried it 20+ times and have not observed anything different. I couldn't see a pattern on why the SigBlk of gnome-panel is different between different runs. It keeps switching - i.e. even if one run is "good", if I kill it (in the same gnome-session), the next run might be "bad".
From the 0-SigBlk xfce4-terminal, I can launch smuxi-frontend-gnome and it will also have 0 SigBlk.
smuxi¶
TL;DR I am able to get smuxi-server,smuxi-frontend-gnome working reliably by repeatedly (killing gnome-panel, and re-starting xfce4-terminal) until the latter has a 0 SigBlk, then launching smuxi from the terminal rather than from gnome-panel.

"smuxi-frontend-gnome always has the same non-0 SigBlk as gnome-panel" actually this directly contradicts the dump I posted, it seems they are similar but not exactly the same.

I think this simply means that mono/smuxi is never touching it's signal block mask itself but simply uses the inherited mask. gedit on the other hand always seems to clear it. At least in the gedit case there should be code inside doing this...
