Bug Description

Binary package hint: scim

When scim is active sometimes applications no longer receive/accept any input from keyboard.

After some experimentation I came up with the following procedure to reproduce this:

* Open firefox and any other window
* In firefox press ctrl-n immediately followed by alt-tab, focusing the other window
* A new firefox window apears and the input is frozen.

I'm using scim 1.4.7-1ubuntu2 and X11/Dynamic set to true (see Bug #66104).

.xinput.d/de_DE is a symbolic link to /etc/X11/xinit/xinput.d/scim and scim is started automatically when I log in.

After stopping scim via the applet sometimes the application continues to work normally, sometimes it crashes immediately and sometimes it crashes shortly afterwards.

I have to following scim-related packages installed

$ dpkg -l *scim*|grep '^.i'

I'm seeing the same thing happening. Attached the requested files.

After closing scim gnome-panel and wallpaper-tray crashed (maybe others?) but firefox seems to have stayed put.

Thanks for sending the files, however your problem is known and
different from this bug:

$ grep "Dynamic" etc/scim/config
/FrontEnd/X11/Dynamic = false
$ grep "Dynamic" home/jono/.scim/config
/FrontEnd/X11/Dynamic = false

You problem has been analyzed in bug #66104, please look at that
bug report to see the workaround for the bug.

This is expected. Closing scim in XIM mode will affect other
applications that used scim.

Yes, your configuration indeed has /FrontEnd/X11/Dynamic set to true.

However, there is something very wrong. In scim.info:

The correct setting should have $XMODIFIERS=@im=SCIM. Actually, I am
surprised that scim works at all with these environment variables.
It seems you are not using the im-switch system to set up scim. Please
don't set up scim by yourself and use the system provided im-switch
system, and see if you still have the problem with correct setting.

Thanks,
Ming

scim-bug-files.tar Edit (20.0 KiB, application/x-tar)

I saw bug #66104's description and was able to duplicate the lockup noted in that bug. when I closed scim, I was able to input text again. gnome-panel crashed when I did that.

I am responding to this bug because it is related to problems in gutsy. I was using scim input for Chinese without problems with feisty. Then I upgraded to gusty and starting seeing lockups in gnome-terminal and in oowriter and in nautilus. I don't think I've noticed as many in firefox... can't think of a firefox lockup off the top of my head...

so just saying that this is a problem on more than one system. I am going to install from the CD once the release candidate is out and see if that fixes anything.

~$ grep "X11/Dynamic" /etc/scim/config
/FrontEnd/X11/Dynamic = false

~$ grep "X11/Dynamic" ~/.scim/config
/FrontEnd/X11/Dynamic = false

~$ echo $GTK_IM_MODULE
xim

The problem described in bug #66104 applies to gutsy. Actually it will affect a default gutsy install, as you've found out (and as far as I know, the release candidate won't fix that problem).

I've updated the description in #66104 to make it more clear. Please read that bug again and see the workarounds provided there. Also please put further discussion in #66104 as well.

Why? The original reporter said very clear that his problem is not the
same as bug #66104.
