first I should clarify, that lupdate-qt4 does not deal with Python sources. 
That's the job of pylupdate4. The later will extract the translatable strings 
from Python sources (*.py) and form files (*.ui). If called from eric4 
(through the context menu of the translations tab of the project viewer) a 
temporary .pro file is generated by eric4 containing just the file entries 
appropriate for the selected action (current file, all selected files or all 
files of the project). More explanations below.

That is strange. I would need the sources to analyze it.

You may ignore this. It just means, that linguist cannot show the source for 
the file being translated. It seems, that linguist gets confused, if the 
translation file (.ts) is not in the root directory of the project.

Please send the .ts file generated by lupdate-qt4 for analysis.

That is to be expected due to the missing context.
