Hmm - I'd really prefer not to have to change the locale for anything but
the conversion. We have multiple threads running in parallel, and it's not
possible to say if one of those is trying to get a localized version of a
string at the same time as the locale is changed... Of course, the risk
would probably not be huge, but it's still there...

For reference, I've created an issue in the Jira system now - it can be
found here:
