Was that with a full rebuild? I had this same problem as well until I rebuilt libbe.so.

What I need is a backtrace (by typing bt in the crash window) not a syslog. Also, it is likely that you need to rebuild libbe.so as anevilyak suggested. I assure you that I have tested Deskbar in all modes including bottom of the screen and it should work.

Hi, I rebuild hrev44830, but Deskbar still crashes. backtrace is added.

Hi, I try hrev44840, Deskbar still crashes. But moving Deskbar to up/down (right/up and right/down corner of screen) seems to work, moving to left or moving as a bar don't work.

Hi, I rebuild hrev44840 with gcc2 / gcc4 hybrid, it works! I think this is gcc4 problem.

Should now be fixed in hrev44845.
Rebuilt in gcc4 and the bug became obvious. The separator was being added in vertical mode erroneously because the variable was not set to NULL initially, then switching mode it attempted to delete a non-NULL but garbage object causing the crash. gcc2 most likely initiated the object to NULL implicitly while gcc4 did not which is why the bug only showed on gcc4.
Comment on this ticket if the bug is not fixed for you and I'll re-open.
