Blender Version
Broken: 2.76

Short description of error
When using the ImportHelper or ExportHelper classes to enable a file browser dialog on an operator, enabling file extension filtering by setting the 'filter_glob' variable with a large amount of extensions will cause unicode errors such as:

File "C:\Program Files\Blender Foundation\Blender\2.76\scripts\startup\bl_ui\space_filebrowser.py", line 74, in draw
  row.label(params.filter_glob)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd2 in position 68: invalid continuation byte

Exact steps for others to reproduce the error

In a text area, load in the python template "Operator File Import"
Change line 32 (originally the line is 'default="*.txt",' to a long string. I used:

  default="*.cin;*.jpg;*.tga;*.bmp;*.rgb;*.dpx;*.sgi;*.tiff;*.png;*.hdr;*.dds;*.j2c;*.pdd;*.tx;*.tif;*.psd;*.psb;*.jp2;*.exr;*.jpeg;*.rgba",

Run the script.
The errors are triggered when the mouse moves in and out of the text input field.
