Bug ID: 501191
Summary: Konsole crash when double clicking on vertical scroll
bar
Classification: Applications
Product: konsole
Version: master
Platform: Other
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: konsole-de...@kde.org
Reporter: j...@keelhaul.me.uk
Target Milestone: ---
SUMMARY
Double clicking anywhere on the Konsole scroll bar causes a crash. This does
not seem to be related to the scrollbar position or how much text is displayed,
the same happens in an empty window. DrKonqi does not start, but the backtrace
from gdb is:
Thread 1 "konsole" received signal SIGSEGV, Segmentation fault.
