Description Lawrence Lim 2004-11-23 20:23:16 EST
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 2004-11-23 21:10:53 EST
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.

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 03:37:36 EST
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.

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 Ngo Than 2005-02-22 09:22:42 EST
it's fixed in qt-3.3.4-5, which will show up in rawhide soon
