 Hi Marco,

 This is with the old labeling engine (available through the vector
 property dialog).

 When opening the qgis project in
 http://trac.osgeo.org/qgis/attachment/ticket/3467/BloatedPS.tar.gz I got
 "This project file was saved by an older version of QGIS. When saving this
 project file, QGIS will update it to the latest version, possibly
 rendering it useless for older versions of QGIS." (1.6.0 trunk).
 The project updated correctly to 1.7.

  I can confirm the bug with several fonts (Ubuntu, Arial) at several
 scales, with the label engine which is available through the vector
 property dialog. The labelling-NG works perfectly.

 Confirmed with following readers: Adobe Reader 9.4.2 (11 Febr 2011) and
 Okular (Kubuntu 10.10 64 bits). Okular is smarter than Adobe Reader (gives
 a low-resolution overview) but still takes 100% of one core for a while.


 Hint to see the problem better: put a colored buffer. You'll see that the
 buffer is made of many displaced identical letters. The pdf file size is
 about 40 times bigger than with labelling -NG ( 307ko vs 7.7 ko).

 I changed the priority as it does not crashes qgis; it produces corrupted
 (output) data but does not corrupt input data.

 I guess should be fixed when labelling-NG will deprecates the old
 labelling engine.

 Mayeul
