It looks like sometime in the last few days Firefox and Thunderbird versions were bumped.
I've unfortunately got a problem (oddly enough, the same or very similar problems) with both: 1:09.75 In file included from /var/tmp/portage/www-client/firefox-60.3.0-r1/work/firefox-60.3.0/ff/media/libav/Unified_c_media_libav0.c:29:0: Exception in thread ProcessReader: Traceback (most recent call last): File "/usr/lib64/python2.7/threading.py", line 801, in __bootstrap_inner self.run() File "/usr/lib64/python2.7/threading.py", line 754, in run self.__target(*self.__args, **self.__kwargs) File "/var/tmp/portage/www-client/firefox-60.3.0-r1/work/firefox-60.3.0/testing/mozbase/mozprocess/mozprocess/processhandler.py", line 1028, in _read callback(line.rstrip()) File "/var/tmp/portage/www-client/firefox-60.3.0-r1/work/firefox-60.3.0/testing/mozbase/mozprocess/mozprocess/processhandler.py", line 944, in __call__ e(*args, **kwargs) File "/var/tmp/portage/www-client/firefox-60.3.0-r1/work/firefox-60.3.0/python/mach/mach/mixin/process.py", line 86, in handleLine line_handler(line) File "/var/tmp/portage/www-client/firefox-60.3.0-r1/work/firefox-60.3.0/python/mozbuild/mozbuild/controller/building.py", line 672, in on_line self.log(logging.INFO, 'build_output', {'line': line}, '{line}') File "/var/tmp/portage/www-client/firefox-60.3.0-r1/work/firefox-60.3.0/python/mach/mach/mixin/logging.py", line 54, in log extra={'action': action, 'params': params}) File "/usr/lib64/python2.7/logging/__init__.py", line 1238, in log self._log(level, msg, args, **kwargs) File "/usr/lib64/python2.7/logging/__init__.py", line 1293, in _log self.handle(record) File "/usr/lib64/python2.7/logging/__init__.py", line 1303, in handle self.callHandlers(record) File "/usr/lib64/python2.7/logging/__init__.py", line 1343, in callHandlers hdlr.handle(record) File "/usr/lib64/python2.7/logging/__init__.py", line 766, in handle self.emit(record) File "/var/tmp/portage/www-client/firefox-60.3.0-r1/work/firefox-60.3.0/python/mozbuild/mozbuild/controller/building.py", line 555, in emit self.fh.write(msg) UnicodeEncodeError: 'ascii' codec can't encode characters in position 146-148: ordinal not in range(128) Has anyone run into this? I checked my locale, it's set correctly as utf8. This machine has also been kept up to date (it's not the same machine that I posted about a python issue earlier.) I don't know if Thunderbird is stopping at exactly the same place, but it was the same "ordinal not in range" error. Dan
