Then I installed the debuginfo packages for kmail, glibc and glibc-devel. And finally I created a callgrind graph (attached) while KMail was starting. "Normal" start-up time for KMail with this bug is about 30 seconds. Despite the fact that all the required debuginfo packages had been installed, valgrind did not find many of them (or those were not created properly). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
