#166 SIGSEGV on debian sid when csladspa package is installed

[Forrest Cahoon]

Sonic Visualiser (installed from the 1.9cc deb linked on the web page) started crashing on startup on my debian sid machine, when previously it worked fine.

I built a debug version from the Hg sources (downloaded 2012-05-02) and was able to reproduce the problem: here's the backtrace from the crash:

Program received signal SIGSEGV, Segmentation fault.

I removed the csladspa package (version 1:5.17.6~dfsg-2 from the official sid repository) from my machine, and both my debug version and the deb-installed version of Sonic Visualiser started working again.
