Description Lawrence Lim 2004-11-24 01:23:16 UTC 
Description of problem:
In any event where httx shut down unexpectedly or crash, it will cause
any Qt application which has connection to, to crash.

Shutting down htt_server in GNOME desktop environment, with GTK
applications open does not cause the GTK applicatipons to crash.

Version-Release number of selected component (if applicable):
im-sdk-12.1-9.EL

How reproducible:
Always

Steps to Reproduce:
1.killall httx
2.killall htt
3.service iiim start
4.LANG=zh_CN.UTF-8 httx &
5.LANG=zh_CN.UTF-8 kedit &
6.kill -9 [pid of httx]
  
Actual results:
kedit crash

Expected results:
kedit should not crash

Is it a httx specific problem? does other XIM server work fine on that?
Comment 2 Lawrence Lim 2004-11-24 02:10:53 UTC 
Thanks for pointing that out. :)

Tried with XIM server and yes, this is not httx specific as sending
SIGSEV to XIM server causes kedit to crash as well.

Comment 4 Than Ngo 2004-11-24 17:33:14 UTC 
i have taken a look in backtrace, the crash happens in DestroyIC((XIC) ic)!
is it not a bug in xorg-x11?
Comment 5 Leon Ho 2004-11-25 08:37:36 UTC 
I am not sure because gtk+ calls DestroyIC() when XIM server closes as
well and it does not crash. AFAIS briefly, the destructor did check if
ic exists.
Comment 6 Than Ngo 2004-11-29 13:57:06 UTC 
Leon, have you tried to contact to the qtimmodule author, YamaKen? i have sent
him an email but did not get any respond since a week.
Comment 7 Than Ngo 2005-02-22 14:22:42 UTC 
it's fixed in qt-3.3.4-5, which will show up in rawhide soon
