getAPIVersion invalid literal for int() with base 10: 'dev0'

[anonymous]

While using TracXMLRPC-1.1.7.dev0 we get the following error:

It seems the 'dev0' string ist not allowed.

Eclipse mylyn doesn't work anymore without an correct API version string.

I've fixed it with:
Line 339 in api.py

return map(int, tracrpc.__version__.split('-')[0].replace('.dev0', '').split('.'))
