Bug#928710: drkonqi: segfault after using reload button to get backtrace for dolphin
Package: drkonqi
Version: 5.14.5-1
Severity: normal
dolphin crashed, and I didn't have sufficient debug sym installed. I
installed them, and then hit the "reload" button to re-do the backtrace,
at which point drkonqi crashed.
Backtrace below:
Application: drkonqi (drkonqi), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
