Bug#889919: ksystemlog: SIGSEGV in QAction::setEnabled
Package: ksystemlog
Version: 4:16.08.3-1
Severity: normal
Tags: upstream
Dear Maintainer,
Steps to reproduce:
1. Run ksystemlog
2. Click "Kernel log"
3. Ctrl-T to open a new tab.
4. Click X to close window.
5. Get a "Segmentation fault" message and/or core dump.
Reported for version 16.08.3, but also reproducible in Debian sid (17.08.3).
Full backtrace attached. Core dumps available upon request, though they
are 53M-57M in size.
Sincerely,
Nathaniel Beaver
