Comment 4 for bug 528692

This seems to have been fixed on Epiphany but the bug still occurs on Gnash.

Hence this is probably, as suggested before, something each application should fix itself: i.e. they should drop the use of the old python classes.

For reference, here's a quote form my opening report:
"I found two other bugs referencing this message but it seems each application has taken a particular (instead of generalised) fix for this.
Then again, someone did mention in one of those that the problem is related to apps using the old python classes... So... maybe it is each app's job to do it...?
If so, please let me know so I can report this to the apropriate applications.

Here are the two other bugs:
* Bug #377226 - https://bugs.launchpad.net/debian/+source/listen/+bug/377226
* Bug #114053 - https://launchpad.net/bugs/114053"
