I've tried rebuilding scite, but it still segfaults.

Unable to reproduce the crash with scite_1.76-1 with kernel 2.6.31-8-generic

[Stefan Weil (ubuntu-weilnetz)]

Can be reproduced with karmic and kde netbook desktop.
No crash occurs with gnome.

Call stack:

<signal_handler_called>
fork_exec_with_pipes (glib2.0-2.22.3/glib/gspawn.c:1199)
IA__g_spawn_sync

fork_exec_with_pipes creates a new process kde4-config.
scite obviously gets a signal (which signal?) when this
new process terminates (?) and fails in the signal handling
with SIGSEGV. This explains why the stack below
IA__g_spawn_sync is not always the same (sometimes
the crash comes a little later).

There seem to be other packages affected by the same kind of
bug, just look for fork_exec_with_pipes.

[Stefan Weil (ubuntu-weilnetz)]

scite receives a SIGCHLD signal and crashes in the handler.

Running scite from gdb with SIGCHLD not passed to the program
makes it work.

[Stefan Weil (ubuntu-weilnetz)]

The crash can be avoided by unsetting GTK2_RC_FILES:

 GTK2_RC_FILES= scite

It can be forced by setting it to a certain value:

 GTK2_RC_FILES=/usr/share/themes/QtCurve/gtk-2.0/gtkrc scite

Of course you must have installed /usr/share/themes/QtCurve/gtk-2.0/gtkrc
to get a crash.

[Daniel Hahler (blueyed)]

Yes, that's the bug I'm facing.

Thank you for investigating.

So, is this a bug with Scite (and the other applications crashing in a similar way), or is it a glib bug (where fork_exec_with_pipes) appears to come from?
