Version: 1.9.6 (enterprise 20070904.708012) (using KDE 3.5.8 "release 22.3" , openSUSE ) Compiler: Target: i586-suse-linux OS: Linux (i686) release 2.6.22.13-0.3-default when clicking on a link in a mail, konqueror should be opened. But instead Kmail hangs and must be killed.
Strange problem, I've never seen this. 1. Can you try a newer version? Your enterprise version is old, it was work-in-progress at that point 2. Does this happen in other KDE applications as well? 3. Can you try to interrupt KMail with GDB while this problem happens to get a backtrace? I somehow doubt that this is KMail's fault, as KMail just calls KRun.
strange, it works again. But I don't think that I have changed anything :-)
