kmail crashing - how to uninstall?

[Rory Gleeson]

I've been having a problem of kmail crashing (signal 11) in Gnome or KDE
desktop in  Fedora Core 2 Test 3 since installation.  It opens and then
immediately crashes every time.

I'd like to uninstall it but it seems like it's bundled on the isos with
other kde programs.

Can someone tell me what KDE file kmail in bundled in?  And is it safe
to uninstall it, as I don't know what else is bundled with it.  

I'm thinking of removing that package and them downloading that package
from the development tree and installing it, to see if it resolves any
issues.

I'm new to removing/adding packages in Linux, so any tips would be
welcomed.

Thanks,
Rory
