Smuxi

this happens to me on linux (debian 5.0 minimal) aswell.

My system configuration was like this before solving the issue:
I had a debian 5.0 minimal. Installed smuxi from backports deb file.
I started smuxi using X11 forwarding to another machine. -> Problem occured.
I tried to compile smuxi on that machine. I had to install libgnome2.0-cil.
After installed that package smuxi worked out of the box. Seems like there is a missing dependency.

On Debian I could track this issue down to missing librsvg2-common, as that ships the SVG loader support for GTK+. I will add this package to the dependencies. No idea why it would file on Windows though, sure it's GTK# 2.12.9? Try reinstalling GTK#...

I reinstalled GTK#, but it still fails.

Today I found a Smuxi user with exactly this problem and I could find the cause of it. If the user had another installation of a GTK+ based application like GIMP or Pigdin then the PATH environment variable will contain different GTK+ versions at the same time. The first GTK+ version that is listed will get used and that one might not have SVG support! I don't really know a solution except removing the other GTK+ installs or change the order in the PATH variable.

Here is a simple test application that can be used to test wether GTK# with SVG support works correctly.

19:59:52 <SilentException> i did a complete uninstall of gtk#
20:00:22 <SilentException> and in add remove programs i had two of them (one was older)!
20:00:42 <SilentException> but i never installed gtk#, first time hearing of it :S
20:01:00 <SilentException> now i removed both and will install again
20:11:02 <SilentException> ok, now i don't have two in add/remove programs
20:11:16 <SilentException> and test program ran ok (with the icon)!
20:11:30 <SilentException> awesome, smuxi also started :)
20:15:20 <meebey> SilentException: for the record, which exact gtk# install/version is now installed?
20:16:57 <SilentException> right now on win 7 i have "Gtk# for .Net 2.12.9"

I can confirm that there is a problem with gtk# 2.12.10, I got this error with it on Windows 7 (x64), after uninstalling and installing gtk # 2.12.9-2 Smuxi works like a charm! Took a look at the gtk# bug tracker, and it is a known bug: //bugzilla.novell.com/show_bug.cgi?id=661405">https://bugzilla.novell.com/show_bug.cgi?id=661405
