#586 Crash on desktop item when "use the same wallpaper" disabled

[Alister Hood]

On my machine pcmanfm (from git, with libfm also from git) crashes every time I click on a folder on the desktop, or right-click on the desktop, if "use the same wallpaper on all desktops" was disabled when pcmanfm was started.

There is no crash if the option was disabled after pcmanfm was started.

I currently have gtk 2.24.11 and glib 2.32.4. I'm not sure how long the problem has been around or if it would still occur with significantly older gtk or glib, because I only started testing with "use the same wallpaper..." disabled after work was begun on #3411306.

This was previously reported in the comments at http://sourceforge.net/tracker/?func=detail&atid=801864&aid=3411306&group_id=156956. I'm no longer having a couple of the problems I reported in that ticket (crashing immediately on startup when starting in gdb with a desktop, and the window staying on desktop 1 if "use the same wallpaper..." is enabled). I don't know whether this is because of a system upgrade, or changes in libfm or pcmanfm.
