Exactly as the title says. I open a clean new file, do Ctrl-S or manually click the save icon and Gaea opens up the major crash dialogue box.
I cannot say since when this has been happening, nor is running Gaea in Safe Mode, CPU Only, after cleanup fixing the issue.
I found a workaround by opening one of the crash recovery files and that allowed me to get the save dialogue.
