[Reportbug-maint] Bug#885969: reportbug: AssertionError (threading, GUI)

[Lorenzo Ancora]

Package: reportbug
Version: 7.1.7
Severity: minor

Dear Maintainer,
sending a bug report without a stable connection to the gateway causes
reportbug to crash with AssertionError, instead of showing the user-friendly
error dialog.

Console OUTPUT: https://paste.debian.net/1003083

"AssertionError: Function should be called in <MainContext of reportbug thread>
but was called in <MainContext of UI thread>"... but assertions should never be
part of the UX. :-)
