[imp] IMP 3.1 segfault

[Iain]

Hi,

I have been having a problem with IMP 3.1 causing a segfault. The segfault 
occurs when I press send-message in the compose window. I have tried this 
with PHP 4.1.2 and 4.2.2. I am using apache 1.3.26 on a Debian Woody system.

I have tried getting a backtrace but am not sure if I am doing the right 
thing:

After running gdb --args apache -X:

Program received signal SIGSEGV, Segmentation fault.

and from running strace apache -X:

rt_sigprocmask(SIG_UNBLOCK, [PROF], NULL, 8) = 0
--- SIGSEGV (Segmentation fault) ---

Is there something else I should do to debug this problem?

thanks, Iain.
