Help : application startup problem on OpenBSD

[Philippe Roussel]

Hi all,

I'm trying to find why SimpleAgenda (contrary to other applications
apparently) blocks on startup on OpenBSD. It seems stuck on polling but
I don't know what's happening.

Here's gdb backtrace :

I tried to inspect the Date value used on frame 7 but I just got a
SIGSEGV and couldn't go further (no gdb guru around here...).

Any help would be greatly appreciated.

Thanks,
Philippe
