I have pushed a change at 7da981b3 that avoids the crash. With this change, the compressed svg icons are used as is, without first uncompressing them. The reason of the crash is still unknown, but it is surely related to the removal of the temporary file and some sort of race condition that your document exploits fully, apparently. -- Enrico
