Comment 14 for bug 1662531

Attached is the output of the extension 'Export > Pre-Process File Save As...' with the (replaced) test version of the script ('prepare_file_save_as - Copy.py') run with lp:inkscape/0.92.x r15365 on OS X 10.7.5 (same crash as with Inkscape trunk on Ubuntu).

The attachment also contains the backtrace of the spawned inkscape process as tracked by the native OS crash reporter (likely the crash is related to mixing without-gui (query-x) and with-gui (verbs) command line arguments (?)).

The original 'prepare_file_save_as.py' from comment 2 does not trigger the crash of the externally spawned inkscape process (AFAICT it opens the modified document in second instance, prompts for saving and saves as with the selected output format as expected).

Both tests had been run separately, with a new document containing a simple stroked and filled rect with rounded corners.
