Package: kernelshark Version: 2.8.3-5 Severity: grave X-Debbugs-CC: [email protected]
Dear Debian kernelshark (trace-cmd) maintainer,
When I perform the following actions in kernelshark in Debian Sid, kernel
shark will crash:
1. Open kernelshark
2. Click the "+" button
Partial traceback is as follows:
