#643 Crash when removing bookmark for folder which doesn't exist

[Alister Hood]

Add a folder to the bookmarks.
Delete the folder.
Click on the folder in the bookmarks, and click OK in the error dialog.
Right-click on the bookmark and choose to remove it. It usually won't be removed.
Right-click on the bookmark again and choose to remove it. Pcmanfm will usually crash - see backtrace below.
I also twice managed to remove a bookmark (again pointing to a non-existent location) from the side panel without crashing pcmanfm, but the bookmark was not actually removed from the bookmark menu...
