Severity: normal
Usertags: progression

Since the upload of matplotlib version 2.2.2-1, apparently the module
NavigationToolbar2Wx from matplotlib.backends.backend_wxagg isn't there
anymore. As I can only assume (please reassign this bug to matplotlib if
I am wrong), this was done intentionally¹, I am filing this bug against
python-bumps: your autopkgtest² fails since than with the following error:

ERROR: Failure: ImportError (cannot import name NavigationToolbar2Wx)
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/nose/", line 418, in
    addr.filename, addr.module)
  File "/usr/lib/python2.7/dist-packages/nose/", line 47, in
    return self.importFromDir(dir_path, fqname)
  File "/usr/lib/python2.7/dist-packages/nose/", line 94, in
    mod = load_module(part_fqname, fh, filename, desc)
  File "/usr/lib/python2.7/dist-packages/bumps/gui/", line
10, in <module>
    from matplotlib.backends.backend_wxagg import NavigationToolbar2Wx
as Toolbar
ImportError: cannot import name NavigationToolbar2Wx

It looks like this bug may be of higher severity if the package stops
working due to this, but as I lack the insight to this package, I file
it as normal. Please investigate the situation.


¹ It looks like instead of NavigationToolbar2Wx it is now available as
NavigationToolbar2WxAgg; see
