Hi friends 
since yesterday I can't open many  .PO files with kbabel
there is a problem with Kbabel  v. 1.11.2
telling  file is not a standard PO file
I have a problem to open k3b.po  and many others in kbabel
but some synchronised file doesn't want to open 
any body can make a try and try to guess the problem ?

Thanks
