Bug ID: 356815
Summary: Crash if you close kate when the print dialog is open
Product: kate
Version: Git
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
Assignee: kwrite-bugs-n...@kde.org
Reporter: santhiar.anir...@gmail.com
Kate crashes if it is closed when the print dialog is open.
Close kate from the command line using "qdbus `qdbus | grep kate`
/kate/__KateMainWindow_1/actions/file_quit trigger" when the print dialog is
open
Reproducible: Always
Steps to Reproduce:
1. Open kate
2. Issue Ctrl + P, and when the print dialog is open,
3. Say "qdbus `qdbus | grep kate` /kate/__KateMainWindow_1/actions/file_quit
trigger" from a terminal
Actual Results:
kate crashes
Expected Results:
kate closes smoothly
I investigated this bug further using a version of kate built using address
sanitizer.
(http://clang.llvm.org/docs/AddressSanitizer.html)
This is actually a use-after-free bug. Please see the report for the stacks at
the access, free and allocation of the memory involved. I shall be happy to
supply any other information that might help fix the bug.
