Bug#334223: kdesktop_lock segfaults if Japanese characters are entered in login dialog, using XIM
Package: kdesktop
Version: 4:3.4.2-3
Severity: normal
After kdesktop_lock --forcelock is started, and the screen is locked, if
Japanese UTF-8 characters are entered, it crashes with a segfault and
unlocks the screen.
This is reproducible 100% on my system.
I have installed packages scim and scim-canna, started using im-switch,
i.e. the following commands are started:
/usr/sbin/cannaserver -u canna
/usr/bin/scim -d
The following environment variables are set:
LANG=fr_FR.UTF-8
LC_CTYPE=ja_JP.UTF-8
XMODIFIERS=@im=SCIM
GTK_IM_MODULE=scim
This configuration works very fine for typing Japanese in any X app,
including KDE apps.
Here is how I can predictably produce the bug:
1- start kdesktop_lock --forcelock (as it is started by KDE's lock
button applet)
2- move the mouse to make the dialog appear
3- type CTRL+SPACE, to activate scim: the scim panel appears, and
"Canna" should be selected as an IM method
4- type a few random characters (not the user password)
5- type ENTER: kdesktop_lock crashes with a segfault, which unlocks
the screen
Maybe this bug appears with other UTF-8 CTYPE locales (not only
Japanese), and other X Input Method (not only scim), but I have not
tested.
