Bug ID: 343264
Summary: Kleopatra randomly crashes in the background,
potentially while dealing with signed emails
Product: kleopatra
Version: 2.2.0
Platform: Gentoo Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: kdepim-bugs at kde.org
Reporter: matthew at mjdsystems.ca
CC: mutz at kde.org
-- Information about the crash:
While I was working on my computer, Kelopatra randomly crashed in the
background (I wasn't even aware it was running at the time). I think I may
have been looking at some signed emails around that time.
I double checked the generated binary, all the null checks are present. It did
fail copying the fpr member of subkeys, and the register holding the pointer
for subkeys had an address of 0x90, which seems weird to me.
I have a core dumped if you have something more you'd like me to poke into, and
I can keep the debug symbols/source code around for a couple of days. I lurk
in #kde-devel as MJD, feel free to ping me.
-- Backtrace:
