Description
I've build the qgis 0.8 on a fc6 system and I've encountered the same problems with measuring tool as described in the https://svn.qgis.org/trac/ticket/449 -- the measured distances are changing chaotically and the numbers are a way off.
In attechments find the layer. The projection should be Projected Coordinate systems/Krovak oblique/S-JTSK. There are three profiles on this layer and the middle one should be 620 metres long. "On the fly" projection is enabled. Measuring tool has a wrong measurements, the scale bar seems to show the length right.

I have upgraded gdal 1.3.2 with the 1.4.0 version and the measuring tool now works fine. Proj is in version 4.5.0, qgis 0.8.
Thanks.
Note:
See TracTickets
for help on using tickets.
Compiling 0.8 branch with proj 4.4.9 and gdal 1.3.1, the proj4 string was not recognized as valid.
Compiling 0.8 branch with proj 4.5.0 and gdal 1.4.0, the proj4 string *was* recognized as valid.
The latest gdal/proj can be downloaded from http://fwtools.maptools.org/
Please note that in 0.8, measurements does not work reliably with projection turned off, but it should do in 0.9. Could you see if it works for you?
