For the record, the crash only seems to happen if there's more than one tab open when you close the window.
Indeed. With multiple tabs, it reproduces on Tumbleweed as well. -- You are receiving this mail because: You are on the CC list for the bug.

The upstream bug report is filed against ksystemlog 18.04, and it mentions that it's reproducible with 16.08.3 and 17.08.3 as well. -- You are receiving this mail because: You are on the CC list for the bug.

This is very odd. Ksystemlog crashes for me when clicking the X button in the title bar, regardless of the number of open tabs in the application. But it is the same crash (i.e. same backtrace), I suppose?
From what I can see in the backtrace, it apparently tries to access widgets that no longer exist, likely because the window is already closed at that point (that likely also explains why it doesn't crash when you quit it via the menu or keyboard shortcut, the window is probably closed later then).
As this apparently is a timing issue, the exact behavior may be different on different systems, maybe the existance of several tabs just makes the crash more reliable... (just a guess though) -- You are receiving this mail because: You are on the CC list for the bug.
