Bug#783875: playonlinux: "Error in POL_Wine", fails to install new programs

[Phil]

Dear Maintainers,

I get the same problem but I'm trying to install Dashlane (a password 
manager), a non-listed program (at least I selected non-listed). The program 
does run after installation but I do still get that error message. After I 
click 'OK' on the error message, it goes to another dialog which shows 
'loading' and seems never to end (it just stays there).

See screenshots for info.

I can confirm that Dashlane is actually installed (on the playonlinux virtual 
drive) but doesn't not appear as an entry on playonlinux.

Phil
