[Bug 50971] Re: kdesu will not start apps

[Nicolai Hähnle]

I got this bug again using an installation of Kubuntu Feisty Herd-2 with
recent updates. Again I attached to the kdesu process, and the backtrace
looks as in my comment just before this one.

This time, I also remembered to attach to the corresponding kdesu_stub
and create a stacktrace:

(gdb) bt

#13 0xb7e92ebc in __libc_start_main () from /lib/tls/i686/cmov/libc.so.6
#14 0x08048bd1 in _start ()

Some shallow further "analysis":

(gdb) up
#12 0x08048ebf in main () at /build/buildd/kdelibs-3.5.5a.dfsg.1/./kdesu/kdesu_stub.c:203
203     in /build/buildd/kdelibs-3.5.5a.dfsg.1/./kdesu/kdesu_stub.c
(gdb) print i
$4 = 0

It seems that not much at all happened during the communication.

If somebody can give any hints as to how I could help track down this
bug, please do tell me.
