Hmm... this is reproducable (still have to find out how) and fetching mail was not involved. The pinentry-qt was blocked for some other reason. The pinentry just looked blocked because I somehow gave the focus back to KMail which was blocked by the pinentry so it looked like the pinetry dialog was still in front which was actually just a missing redraw (if you understand what I mean :). The pinetry dialog was behind the KMail window but got all keystrokes (the + I typed to view the next unread message). I could reproduce it twice, but now I can't again -- the reason might be that one needs some special way to hit the encrypted mail (like deleting the preceding one). No idea but somewhere there seems to be a race condition... Malte, any more insights on this? Are you manage to reproduce it? If so, could you valgrind the crash, maybe? Happened just for me too with KDE_3_3_BRANCH, here it looks like:

*** Bug 93976 has been marked as a duplicate of this bug. *** Created attachment 9050 [details] KMail/gdb output Running KMail under valgrind is simply impossible on my box, but I found a way to reproduce this reliably. Attached is the debug output of KMail running under gdb. I did the following: 0. Seems like the gpg-agent died before for some reason, at least was the $GPG_AGENT_INFO pointing to the wrong place. So kill your gpg-agent for easiest reproducing. 1. Started up KMail. There was a mail selected which had neither a PGP signature nor was it encrypted (line 36). 2. Selected an encrypted mail (line 87). The gpg-agent wasn't around (line 113), so I got the dialog telling me "You just entered an invalid passphrase. Do you want to try again, or cancel and view the message undecrypted?". KEEP THAT DIALOG OPEN. 3. Selected another mail which also didn't show any PGP traces (line 125). Waited till that message was displayed (line 152). 4. Pressed "Cancel" in the still-visible wrong-passphrase-confirmation-dialog: Boom! So the analysis from bug 93976 seems to point to the right direction: KMail tries to process a message which isn't shown anymore. Happens here too, without SpamAssasin and without entering anything into pinentry-qt. *** Bug 106484 has been marked as a duplicate of this bug. *** *** Bug 110266 has been marked as a duplicate of this bug. *** *** Bug 109454 has been marked as a duplicate of this bug. *** *** Bug 111702 has been marked as a duplicate of this bug. *** *** Bug 120142 has been marked as a duplicate of this bug. *** *** Bug 131654 has been marked as a duplicate of this bug. *** *** Bug 118214 has been marked as a duplicate of this bug. *** Moving this to 92737, since it has more votes. *** This bug has been marked as a duplicate of 92737 *** |
Version: 1.7.2 (using KDE 3.3.2, Gentoo) Compiler: gcc version 3.3.4 20040623 (Gentoo Linux 3.3.4-r1, ssp-3.3.2-2, pie-8.7.6) OS: Linux (i686) release 2.6.8-gentoo-r3 KMail (KDE_3_3_BRANCH from yesterday) just crashed, it all went pretty fast so I don't know what actually triggered it. What happened was this: 1. I accidently selected an GPG-encrypted mail in my inbox so the pinentry-qt window popped up. 2. I didn't want to decrypt that mail so I tried to click Cancel. 3. In between the mail fetch interval kicked in and KMail was frozen because SpamAssassin checked a mail. 4. When KMail wasn't frozen anymore, I noticed that for some reason I typed two chars in the pinentry. I clicked Cancel nevertheless again. 5. That stupid dialog popped up which told me that I entered a wrong password [sic] and asked me if I wanted to try again. I clicked Cancel here, too. 6. KMail crashed.
