Description Fabian Hahn 2009-05-19 11:40:28 UTC

If I try to open plain text files (.txt or no extension at all) or images (jpg, gif, png) with gnome-open, which is automatically used when double clicking on such files in nautilus as well, gnome-open hangs.

I figured it could have something to do with mime types, but removing ~/.local doesn't help. Reemerging libgnome or the mime packages doesn't change anything as well.

Reproducible: Always

Steps to Reproduce:
1. touch test.txt
2. gnome-open test.txt
3. top
Actual Results:  
 * the files are not opened (no editor, image viewer, whatsoever)
 * the gnome-open process remains open (observable with ps ux | grep gnome-open)
 * dbus-daemon, gcond2, gnome-session and severall other gnome-* processes start to take up a sum of >30% CPU constantly

Expected Results:  
 * file opens in the appropriate viewer
 * gnome-open terminates at some point
 * no cpu load explosion of dbus and gnome services

Created attachment 191768 [details]
strace -f gnome-open test.txt

This is an strace up to the point where gnome-open seems to enter some kind of endless loop, constantly trying to execute again. At some point I just ctrl+c'd and cut out the first part until the whole thing starts to repeat itself

I think we'll need some profiling data (oprofile/sysprof) to see where dbus & co are spending their time eating the CPU. Could you provide us with that ?

Please get back to us.

Comment 4 Fabian Hahn 2009-11-08 17:26:34 UTC

After some further investigation, I realized that the endless loop was caused by the default application for the problematic filetypes being set to "gnome-open" itself, so I guess it wasn't gnome-open's fault but rather the fault of what caused the preferred application for the filetypes to be set to "gnome-open" (I didn't do this manually for sure...).
I fixed it for me by using Properties -> Open With -> Reset on a file with one of the problematic types. I'll report it should it happen again after an update.
