convert crashed with SIGSEGV in DrawAffineImage()

[Adam Dunn]

Binary package hint: imagemagick

As you can see, this is from an automated crash report, and I was doing multiple things, most of which shouldn't have been using convert (mplayer playing a movie, while make was building something). I'll have to look through my own crash report to find out what happened...

Upon examining the ProcCmdline, it looks like convert was trying to convert an svg from the new speech-to-text package "simon". I downloaded the simon-0.1-alpha-1 (http://sourceforge.net/project/showfiles.php?group_id=190872) package from sourceforge, tried to compile it, and got this crash. You can get the particular svg file from (http://speech2text.svn.sourceforge.net/viewvc/speech2text/trunk/images/icons/applications-other.svg?revision=226&view=markup). I'm not an svg expert, but the file in question seems to render fine in Firefox 2.0.0.11 and Inkscape 0.45.1. Maybe somebody who knows more about svg can determine if this is the fault of the file, or of imagemagick.

Err, sorry, looks like I wasn't compiling it. The only way I can think of that convert would have been reading that file, is if tracker had requested it to be processed. So the call to convert must have come from trackerd, but that doesn't really affect the bug report.

Fix in Debian has been synced since then. Closing as Fix Released.
