it looks method in library causes crash checking if either height or width greater 0 -- bitmap requires both > 0:

i've discovered cause. in xml collapsingtoolbarlayout set:
app:expandedtitletextappearance="@style/transparenttext" and style was:
<style name="transparenttext"> <item name="android:textcolor">#00666666</item> </style> so show text when toolbar collapsed.
turns out styles expandedtitletextappearance , collapsedtitletextappearance need inherit textappearance. style works properly:
<style name="transparenttext" parent="@android:style/textappearance"> <item name="android:textcolor">#00666666</item> </style> just heads else makes same mistake...
update (7/20/2015): bug appears fixed in v22.2.1 of design support library (https://code.google.com/p/android/issues/detail?id=178674)
