deluge-gtk crashes with Segmentation Fault on startup

[Drooling_Sheep]

I've been using deluge 1.3.0-rc2 for a few days now and it has had occasional crashes but been mostly usable. I unchecked classic mode so I could connect to the daemon from another computer, but now when I start deluge-gtk, the window for choosing a daemon pops up for a split second then there's a segmentation fault.

If you're getting a segfault than that's libtorrent dying. Would you be able to run it in gdb and paste the output here?

I installed the libc6-dbg python-dbg and libtorrent-rasterbar-dbg ubuntu packages (maverick)

I ran 'gdb --args python /usr/bin/deluge-gtk'

here is the output

Quit anyway? (y or n) y

I figured out the problem. I usually access this computer via the display :1 which is created by vncserver. something about this setup causes a segfault in malloc, possibly that the extension RANDR isn't on for this display. I do this so I can access a desktop at the same time as I'm running xbmc on :0. I tried running deluge on :0 after exiting xbmc and it works fine.
