Can you add the following line to the beginning of the formatDistance() function in src/gui/qgsmeasure.cpp, recompile, run qgis, load your data and use the measure line tool, and then tell use you get on the console?
std::cerr << distance << '\ ';
This should tell me whether the problem is in the calculation of the length or in the display of the length.

I've done, what you said and it seems that distance and also mTotal values are calculated properly and there is problem to display them. Even if I put to editTotal some string explicitly nothing was displayed. This led me to check if there is some problem with font rendering. When I set Sans Serif font in qgismeasurebase.ui (with Qt Designer) and then rebuild, the problem disapperared. Yuppiii, wow...
I've attached patch which resolves my problem (it only sets Sans Serif font in QgisMeasureBase.ui)
Conclusion: In UI should be set the most common fonts (to avoid similar issues)

This may be a problem with qt4.1.0. I suggest moving to 4.1.1 rather than hard-coding a font in qgis.

It is Qt-4.1.0 related problem. My upgrade to Qt-4.1.2 resolves this problem.
