Reassigning according to provided backtrace.
Comment 14 Igor Raits 2018-09-04 08:54:57 UTC 
I'm not so into C++, but this seems like issue in trojita which is not holding some reference long enough which causes crash.
Comment 15 Jan Kundrát 2018-09-06 15:40:49 UTC 
(Trojita upstream here.)

We're using the C++ bindings for gpgme. That thing is expected to provide a refcounted copy of everything to the callers. I tried to track this down a long time ago, but even with ASAN and stuff, I just wasn't able to pinpoint the real cause. Sorry, I cannot reproduce that on my system :(.
Comment 16 Raphael Groner 2018-09-06 17:39:08 UTC 
Jan, thanks for your statement.
Then, I tend to close here with the resolution WORKSFORME. But let's wait at least for the EOL notification of the F28 branch that should arrive shortly with upcoming freeze for F29.

@Reporter Is this issue still reproducible for you?
Comment 17 Raphael Groner 2018-12-17 14:37:34 UTC 
No reply any more and so far.

I don't remember seeing _any_ trojitá crash for a few months (since upgrade to F29?)
