Summary: deadlock associated with lowpass filter dialog?
Product: kst
Version: unspecified
Platform: Debian testing
OS/Version: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
AssignedTo: kst at kde.org
ReportedBy: timo.lindfors at iki.fi
Version: 1.7.0-1 (using KDE 4.3.4)
OS: Linux
Installed from: Debian testing/unstable Packages
I do not remember what I did exactly but I was editing lowpass filter dialog
properties. I set cutoff frequency to 0.0001 and hit Ok. After that the UI
stopped responding and gdb shows the following deadlock:
