[texworks] Problem with sync and accented characters in file name

[Ignasi]

I'm using texworks last svn version compiled with mingw32-make on  
windowsxp.
I've created a new document and saved it with an accented character in its  
name (I don't do it except today!).

This new file has three pages but sync jumping from source to pdf doesn't  
work.

I was surprised because it worked until now, I've tested with  
miktex-terworks and worked, and changed file name
avoiding accented char and both miktex and my-texworks worked again.

Is it a know behavior? Is it just a problem with my compiling procedure?

May be it's important, I've compiled with qmake and mingw32-make (without  
cleaning)

Best regards,
