I don't think this is a Graphics:Text bug; it looks to me like the issue is that the encoding of the filename sent by the site has not been handled correctly.

Not sure where this does belong, though. The problem could be at the level of receiving and interpreting the site's response (in which case it might be platform-independent, though perhaps dependent on things like the OS locale, default codepage, accept-languages setting, etc), or it could be at the level of passing the filename to the Gtk file dialog (in which case it would be specific to Linux -- and could still be affected by various system/environment settings).

In any case, it sounds like the issue no longer occurs with current versions (though as long as we're not sure what the problem was, or what fixed it, then we can't have much confidence it is truly/permanently resolved).

hi,I supplement more information。

1)test the problem on one machine(the same OS , same hardware...);
2)check out code from https://hg.mozilla.org/releases/mozilla-release code; build with same Compile options. 
3)test result is that FIREFOX_AURORA_54_BASE tag is OK . but FIREFOX_BETA_53_END  tag code is failed。 

so maybe the patch between the two tag?
