When I'm submitting bug report using Drkonqi, I check to remember my login and password to Bugzilla, but when I submit next report, I have to fill it again. In KWallet is folder named (1) containing entry drkonqi_bugzilla with correct login and password, but it doesn't work. It's very annoying.
Well, it works for me. Maybe it's a kwallet bug in the particular version that you are using?
I have KWallet 1.8, KDE 4.7.4, openSUSE 64b. For other applications it works fine...
After upgrade to KDE 4.8.4 it works.
Close it according to comment #3
