[arch-general] CUPS : can't get driver list since last update

[SET]

Hello,

When installing a new printer via cups's web interface, the process blocks 
with an error message close to 'can't get driver list'. At the same time, 
cupsd and foomatic processes consume 25% CPU resources each. This is 
reproducible on two different hosts.

Downgrading cups and/or cups-filters yields the same result.

Some printers stop working with the error message 'filter failed'.

Cups seems broken since last upgrade (today on one host, 2 or 3 weeks before 
on the second host).

Please consider a fix.

Thx.
