Reproduced with Inkscape 0.48+devel r10520 on Mac OS X 10.5.8 (i386)
The measure tool doesn't work on groups (text converted to path results in a group of individual paths [1]).
Ungroup the converted text to measure the paths for the individual converted letters (or enter the group with a double-click or ctrl+enter).

Since the measure tool is new and there is no blueprint available for planned or supported features, marking as 'Wishlist' for now.
