#166 SIGSEGV on debian sid when csladspa package is installed


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.
