Bug#722630: picard: unsatisfiable Depends: python2

[Bob Bib]

Package: picard
Version: 1.2-1
Severity: serious

Dear Maintainer,
'picard' depends on a non-existent 'python2' package;
strangely, it's not specified explicitly in 'debian/control'.

Is it a debhelper bug or something?..

Best wishes, Bob
