Operating System: Linux 4.11.12-100.fc24.x86_64 x86_64

-- Information about the crash:
- What I was doing when the application crashed:
Opened a somewhat large log file. It complained about a couple of long lines.
I scrolled down in the file looking for information relevant for me, and the application crashed.

Comment 1 Sven Brauch 2017-11-09 19:01:47 UTC

Hm, not sure if this crash is related to the file you opened, except if it is parsed as python. Do you have a project open which was still being parsed? Is the crash reproducible?

Comment 2 Justin Zobel 2020-12-17 05:32:43 UTC

Can not reproduce this anymore, but then I no longer have access to the system that displayed the problem in the first place, nor the log file that caused the problem.
