Hi all, There is a threading problem with the extension system. It results in a crash when saving a document and quitting while the save is happening. Have a look here: https://bugs.launchpad.net/inkscape/+bug/967416 I don't know enough about glib's threading to fix this bug. I do not fully understand where the execution flow is going after the fork (/src/extension/implementation/script.cpp, line 1017, _main_loop->run();), nor where the fork is terminated. I hope someone who knows more about this can have a look. I'm afraid it may lead to pretty weird bugs when running time consuming extensions and doing stuff meanwhile. (gdb reports illegal mem accesses when doing stuff while an extension is running, for example). Is this asynchronous extension execution so important, or can we disable it for now to improve stability? regards, Johan
