Bug ID: 421115
Summary: Konsole crashes on large output of dots and numbers
Product: konsole
Version: 19.12.1
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: konsole-devel at kde.org
Reporter: kdebugzilla at 0x5e.se
Target Milestone: ---
SUMMARY
Encountered when running freebsd-update on a remote server, konsole crashed
when the update program printed a progress bar consisting of e.g.
"50650....50660....50670....50680...."
STEPS TO REPRODUCE
1. in bash, run the following example loop: 'i="0"; while [ $i -lt 100000 ]; do
echo -n ".1" && i=$[$i+1]; done'
2. move mouse pointer around over output
OBSERVED RESULT
konsole hangs and crashes after a second or two
EXPECTED RESULT
nothing special
SOFTWARE/OS VERSIONS
Fedora 31 running Sway as window manager
KDE Frameworks 5.68.0
Qt 5.13.2 (built against 5.13.2)
The wayland windowing system
ADDITIONAL INFORMATION
Trying the same thing on a different system with konsole 19.12.1 using KDE
Plasma and same KDE/Qt versions as above *but on Xorg/xcb* does not cause the
same problem
Trying the above loop with only dots does not exhibit the same issue, URL
parsing?
Here's a gdb "thread apply all bt full" from the core dump:
