Comment 22 for bug 804936

I've experienced something similar, Zim 0.62 on Xubuntu 12.04... my current working hypothesis is that the 'could not save' errors emerged when I was working on a note and then ran an rsync process that included the note I was working on. This created the error when the note was in an unsaved state...

Not running the rsync process when I've got unsaved notes seems to sort this... so far so good but I'm going to keep an eye on this...
