Support-v4 library dependency compiles correctly, but crashes at startup.

[rabipelais]

Adding as a dependency [com.android.support/support-v4 "21.0.0" :extension "aar"] and importing a corresponding library (e.g. (:import (android.support.v4.view ViewPager)) causes the program to compile correctly, but crash at startup (deployed with lein droid doall to a Genymotion emulator). Lein tree also shows the lib is loaded. I referenced this in issue #145
Here is a minimal repo for reproduction: https://github.com/rabipelais/supportv4-test

It seems to happen with all versions of the v4 library.
If I however misspell the import, for example (:import (android.support.v4.view ViewPagerfoooooo)), the error is correctly caught at compile time.

Logcat of the crash:

It appeared to be a problem with DEX, and it solved itself after some clean-and-compile cycles, so I think this can be closed.

Great to hear!
