Comment 8 for bug 1278599

> FYI, if you run ./checkmodels without parameters it should find the models currently used by Onboard and print some more information

   $ ./checkmodels

All looks well, I presume?

My home partition has ample space (as do root and storage partitions), although I did have some trouble with Thunderbird filling up my home partition several months ago. Perhaps the file was saved then? I've experienced a few unclean shutdowns over the months, so that's a possibility. Also, my home and root partitions *are* formatted ext4.

Agreed!

Thank you for all your work on this, It's much appreciated. :-)
