[DRE-maint] Bug#1054256: ruby-blade: uninstallable in unstable (ruby-blade : Depends: ruby-thin (>= 1.6.0) but it is not installable)

[Antonio Terceiro]

Package: ruby-blade
Version: 0.7.1-4
Severity: serious
Justification: uninstallable

After the last upload, ruby-blade ended up with a dependency on
ruby-thin, which does not exist.

Selected version '0.7.1-4' (Debian:unstable [all]) for 'ruby-blade'
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 ruby-blade : Depends: ruby-thin (>= 1.6.0) but it is not installable
E: Unable to correct problems, you have held broken packages.

The correct dependency would be on `thin`.

This is actually caused by a bug in gem2deb (unreported), which was not
finding the correct mapping between gem names and Debian package names
for architecture dependent packages. In any case, ruby-blade will need a
no changes upload to be rebuilt once gem2deb 2.2, just uploaded, is
available.
