compiz crashed with SIGSEGV in IconTexture::~IconTexture()

[Jason Warner]

Binary package hint: compiz

while using dash, searching for applications to launch, I can get it to crash as long as I use it long enough. Have not found way to make it crash consistently, but once it crashes it takes down unity
