[SOLVED?]xfdesktop segfaults

EDIT: This problem seemed to fix itself. I installed the entire xfce group, as well as downgraded to a non [testing] system. I'm not sure what fixed it, but it works now (started via xfce4-session now), but I don't know, I suspect it could still be a bug if I undid that, oh well.

I don't use the full XFCE DE, I use Openbox, but I want to use xfdesktop to manage my desktop, but ever time I try to start it it immediately segfaults:

xfdesktop[26697]: starting up
Failed to connect to session manager: Failed to connect to the session manager: SESSION_MANAGER environment variable not defined
[1]    26697 segmentation fault  xfdesktop

I don't think the SESSION_MANAGER thing matters, but maybe it does, I don't know. I tried recompiling it, that didn't fix anything. Also, thunar works just fine, if that means anything. Any ideas? I've never known how to troubleshoot segfaults, they don't make much sense to me, and I never know what to try, but maybe someone here has some good ideas Also, it worked a while back, but it's been broken for at least a month now.

Re: [SOLVED?]xfdesktop segfaults

It will probably help if you can provide more info. There are some steps here from the xfdesktop maintainer on how to debug an xfdesktop crash, or at least how to get more info: http://spurint.org/projects/xfce4-debugging/#xfdesktop

From there, maybe you can compare yours to the entries in the xfce bug tracker that match up with a "xfdesktop segfault" keyword search: https://bugzilla.xfce.org/buglist.cgi?q … p+segfault

Re: [SOLVED?]xfdesktop segfaults

Thanks for the info chr0nik I did a backtrace and here's the output:

(gdb) run

Unfortunately, I checked Xfce's Bugtracker and Google, and there were a few people that had similar problems in the past (way past, like 2008), and some claim that recompiling fixed it, but nothing that would help me solve this that I could find. Unfortunately, I already tried that and it didn't work. I'll mess with it a bit more though, but I'm not optimistic at this point...Any ideas for alternatives? PcmanFM crashes too much, and I tried Gnome 2's Nautilus from Mate DE, but setting the wallpaper doesn't work from that (unless I'm missing a package, I didn't want to install the whole DE, just Nautilus).

Re: [SOLVED?]xfdesktop segfaults

What do you need xfdesktop for?  When I tinkered with openbox briefly, I used nitrogen to set wallpapers. I believe idesk provides a means for desktop icons and wallpapers. Both are well documented on the arch wiki.

Regarding your segfault, if you can't find anything similar & current and no one offers any suggestions, submit it to Xfce's bug tracker.

Re: [SOLVED?]xfdesktop segfaults

I tried Idesk, and it works, but it's not quite what I want. Idesk lets you add launchers on your desktop, but what I want is a desktop manager that displays all the files in my ~/Desktop folder. I'll figure out a good solution eventually, and in the meantime I'll just deal with PcmanFM's bugginess. But yeah, I'll submit it on their bug tracker, and hope something good comes out of that, but for some reason it seems like this bug will be impossible to reproduce, considering I haven't seen any other threads about it. Oh well, thanks for the help anyways

EDIT: Bug report: https://bugzilla.xfce.org/show_bug.cgi?id=7937
