Crash while checking Google Apps account

[hackel]

I am using mail-notification from Ubuntu (5.4.dfsg.1-1ubuntu1) and whenever I run it to check my Google Apps/Gmail account, it will eventually crash. I decided to run it through gdb and this is what I got (sorry no debug symbols):

Program received signal SIGPIPE, Broken pipe.

I realize this doesn't seem very helpful, so I will try to compile it myself and see if I can reproduce it.

I have attached another backtrace from an unstripped binary, however it appears to be a completely different issue! SIGABRT instead of SIGPIPE, having nothing to do with gnutls...

mail-notification: ../../src/xcb_io.c:176: process_responses: Assertion `!(req && current_request && !(((long) (req->sequence) - (long) (current_request)) <= 0))' failed.

I guess these should be split into separate bug reports, though I have not been able to isolate the issue, nor have I figured out what is triggering it. Any help in the debugging process would be appreciated.
