This also appears to fix both the G12 and G5X.
That seems like a good approach to me. Fixes both opening text files and running modules from filebrowser for me on sx160

I only tried text files, but there's no more crash/blank screen here either.

Somewhat unrelated, one of my cams happened to have a file with a special size, shown incorrectly in the size column. Filesize in bytes also visible on the attached screenshot.

Thanks, I'll check this in later.

I thought we'd squashed the size issues - do you know the actual size in bytes that caused this?

I'd like to differentiate thumb2 D6 and D7 modules, to prevent D6 modules from crashing D7 cameras. My proposal would be this:

No objection from me.
