Version:           3.5.7.4 (using KDE KDE 3.5.7)
Installed from:    Debian testing/unstable Packages
OS:                Linux

I've been trying to install Kopete from the unstable repository but it keeps crashing. On multiple versions.
The stable works just fine but when I try an unstable build it tells me it crashed and caused the signal 11(SIGSEGV).
Tried running from console and with --noplugins and I get the same same thing.
The application loads, seams to connect then, as it displays the Yahoo! password prompt it crashes. I have a Yahoo!, an MSN and a Jabber account in Kopete. None have the password saved in preferences.
The same builds seam to work just fine on other computers I've tried on.
