Subject: [libxi6] All Qt3 apps segfault since libxi6 version 2:1.3-2

Date: Thu, 4 Feb 2010 03:45:15 +0500

[Message part 1 (text/plain, inline)]

Package: libxi6
Version: 2:1.3-2
Severity: important

An attempt to launch seemingly any Qt3 app (tried at least qtconfig-qt3 and
knutclient) inside a vnc4server session results in a "Segmentation fault" error
when libxi6 2:1.3-2 is installed:

$ qtconfig-qt3
Segmentation fault
$

In dmesg:
[ 7001.234225] qtconfig-qt3[9604]: segfault at 4 ip 00007fa5e618c347 sp
00007fff7198f2d0 error 4 in libXi.so.6.1.0[7fa5e6184000+f000]

After a downgrade of libxi6 to 2:1.2.1-2, all the apps run fine:

$ qtconfig-qt3 
Xlib:  extension "XInputExtension" missing on display ":1.0".
Failed to get list of devices

After these messages the application proceeds to launch normally, shows the GUI
and works just fine.

Any chance you could install libxi6-dbg, libxext6-dbg and libx11-6-dbg,
run qtconfig-qt3 under gdb, and get a full backtrace when it crashes?

Cheers,

Nevermind, I reproduced it here.  qt is doing bad things, but we
shouldn't crash.
