Thanks for the fast testing!
The patch has been committed to the qt4-x11 debian packaging 
repository[1], and will be in the next upload to unstable.

I see.

As also said in #623185, note that switching from 'generic' to the 'sh' 
architecture is binary incompatible, so you will need to rebuilding 
every package depending on libqtcore4 after the qt4-x11 upload carrying 
this fix is uploaded.
