Thanks Detlev. I'm running the svn checkout, updated just now, on a system
with no ~.eric4/ or .config/Eric4/, and that change brings me to a different
error:

Original exception was:
Traceback (most recent call last):
  File "/home/darren/Projects/eric4/UI/BrowserModel.py", line 113, in
headerData
    if orientation == Qt.Horizontal and role == Qt.DisplayRole:
RuntimeError: maximum recursion depth exceeded in cmp
Error in sys.excepthook:
Traceback (most recent call last):
  File "./eric4.py", line 111, in excepthook
    logFile = os.path.join(unicode(Utilities.getConfigDir()),
"eric4_error.log")
  File "/home/darren/Projects/eric4/Utilities/__init__.py", line 980, in
getConfigDir
    if sys.platform == "win32":
RuntimeError: maximum recursion depth exceeded in cmp
