 For me only if the cache render is enabled.

 Before crash, the terminal displays this message:
 {{{
 "Warning: QPaintDevice: Cannot destroy paint device that is being painted
 Segmentation fault"
 }}}

 This message is displayed from

 /home/brushtyler/Projects/Work/Faunalia/qgis/qgis_unstable/src/core/qgsmaplayer.cpp:
 848
 {{{
 delete mpCacheImage;
 }}}

 So I think that when the render is disabled the crash is related to a
 different issue.
