Every time i start a nightly build from m-i or m-c on an openbsd box, those two exceptions are spun:

Dunno if it's specific to OpenBSD environment (i dont use an UTF8 locale) but would be nice to have hints to debug that.

Apparently, there is an OS-level error, but we fail when attempting to convert the error message to a string. Most likely, the error is thrown from within this call: https://dxr.mozilla.org/mozilla-central/source/toolkit/components/search/nsSearchService.js?from=nsSearchService.js#4894

Could you launch Firefox with option toolkit.osfile.log? This will activate OS.File logging, which might be able to tell us more about the error.

My best guess, so far, is that the profile directory is at a path that contains a non-ascii char, on a non-UTF8 locale, which is something we don't know how to handle on Unix.

hm there's nothing special to the paths used when finding the profile:

The only specific things i have in my env:

LC_CTYPE=fr_FR.ISO8859-15
LC_MESSAGES=fr_FR.ISO8859-15

Comment 3

[Landry Breuil (:gaston)]

But this is related to the locale since LC_ALL=C doesnt show both errors. I dont even have dirs/files in my homedir/profile with accentued/weird chars.

Comment 4

[David Teller [:Yoric] - still alive but not very active]

What happens if you change LC_MESSAGES to C but keep the rest to fr_FR?

Comment 5

[Landry Breuil (:gaston)]

The exception is not shown if i only have LC_CTYPE set to fr_FR.ISO8859-15.. but LC_MESSAGES is used to tell the applications i want messages displayed in french :)

Oh well, locale handling has always been a nightmare.
