[JDEV] Groupchat 1.00 crash

Fri Oct 13 08:29:58 CDT 2000

Hi everyone,
     I've installed groupchat 1.00 on Intel Red Hat 6.1 and I can cause it
to crash when I use JabberIM to invite another user to join a groupchat.
The groupchat debug and gdb backtrace seem to indicate a bug in etherx?

Debug output from "gbd groupchat core" follows....

This GDB was configured as "i386-redhat-linux"...
Core was generated by `/usr/local/bin/groupchat -D -s test
conference.us.att.com'.
Program terminated with signal 11, Segmentation fault.

Etherx 1.0.1

Groupchat debug output up to the segmentation fault follows....
