Bug ID: 396332
Summary: Segfault when moving a thread when new messages arrive
into the same thread
Product: trojita
Version: git
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Core
Assignee: trojita-b...@kde.org
Reporter: j...@kde.org
Target Milestone: ---
I started dragging a thread and one standalone unthreaded message; I was going
to move them to another mailbox. Another message arrived in the meanwhile. That
message was going to become a part of that existing thread that I was dragging.
Here's a backtrace. There was no assert crash, just a segfault:
