           Summary: Kopete crashes when trying to display tex image after
                    disabling tex plugin
           Product: kopete
           Version: 0.12.7
          Platform: unspecified
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kopete-bugs kde org
        ReportedBy: Regnaron web de


Version:           0.12.7 (using 3.5.9, Gentoo)
Compiler:          Target: x86_64-pc-linux-gnu
OS:                Linux (x86_64) release 2.6.25-gentoo-r7

Steps to reproduce:

1) Enable latex plugin (KopeTeX) for kopete
2) Open a conversation with someone
3) Disable the latex plugin (the chat session needs to stay open)
4) Type some tex formula (e.g. $$a_b$$) [You need to type at least $$a_b$ to make it crash.]
5) Click on Tools and see kopete crash with the following backtrace:

Using host libthread_db library "/lib/libthread_db.so.1".
