When I start monodevelop, the splash screen appear, and after a few seconds the process write this on the terminal and ends: Unhandled Exception: GLib.GException: Unrecognized image file format in <0x00084> Gdk.PixbufLoader:Close () in <0x00198> Gdk.PixbufLoader:InitFromAssemblyResource (System.Reflection.Assembly assembly, System.String resource) I can provide more info (backtraces and such) if needed
Can you please report your 'emerge info' output, and a backtrace if possible? Thanks.

AHA! I suspected emerge info would show you being on PPC. I've seen someone in #monodevelop getting the same issue on PPC, and i don't think they got it resolved. Concerning the backtrace, the SIGPWR isn't actually where this is dying. libgc uses SIGPWR internally for doing garbage collection. You need to add some ~/.gdbinit lines to ignore those. See http://mono-project.com/Debugging for more details on how to do that. My guess is there are endian issues with getting images from embedded resources, either in the *encoding* of the resources, or in the decoding them at runtime. We can narrow that down if you wouldn't mind tarring up the contents of /usr/lib/monodevelop and attaching it to this bug. If it runs fine on my x86 box here, it's a runtime decoding of things, if it bombs, then the embedded resources are being borked when monodevelop is being compiled. Thanks.

Well, I can confirm that removing my /usr/lib/monodevelop and dropping in yours makes MD still start fine (and if you trojaned your stuff, you've probably just successfully at least gained local non priveleged access to my laptop and are currently using a local root exploit to own me). This means in all likely hood this is a runtime issue on PPC with embedded resources. I'll try to see if i can gain access to one of the dev PPC boxes to do some poking, and if all else fails we'll gather enough info to submit a good bug report upstream about this issue.
I'm also on ppc and I got the same error at startup. Note that I also got this error with Banshee. I can't get it working altough someone else on ppc (see bug #115865) successfully did.

this only seems to be a problem prior to gtk-sharp 2.8.0. i was having the same issue with 2.4/2.6, but i just finished merging 2.8.0 and monodevelop runs fine.
Works on ppc using the latest gtk-sharp-2.8, closing.
