On my system, the gnome font selection dialog sometimes hangs. It seems to depend on the font selected. I've reproduced the problem with gfontsel. I select the font "fixed" from foundry "misc", then click the font information tab and--le voila! The problem keeps me from using xchat as well. A sweep with "google" shows a number of bugs that appear to be related. My gnome-libs version is gnome-libs-1.0.53-1 I've tried this with gdb and two different versions of gfontsel, stopping the program each time with gdb. I generated the following "where" outputs: -- test one -- #0 0x403ab12d in g_hook_insert_sorted () from /usr/lib/libglib-1.2.so.0 #1 0x403ac642 in g_source_add () from /usr/lib/libglib-1.2.so.0 #2

I can't reproduce this exact bug, but I believe that this may be the same problem that was causing guname to go into infinite resize loops when you adjust the column division in the main screen. I've fixed that bug in the latest GTK+ package, so hopefully that fixes this one too.
