Title: BUG: FileDialog wildcard seems to have redundant text in filter.

The file-extensions are to be enclosed in parenthesis. Additionally,
they seem to be enclosed in pipe characters which seems to be
redundant.

A quick look at the documentation (and a search) doesn't tell me anything about what the pipe characters are doing. Removing them seems to work for me. Someone more familiar with this, could look into it.
