Reproduced again on Windows XP (32-bit), Inkscape 0.91 (every 3 tries) and 0.92 (after 10 tries).
On 0.91, I also had a case where the label of the Metadata tab disappeared, and some others where the File type (bottom of the file selection dialog) was more or less scrambled.
Looks like some kind of memory management issue.
