[Pkg-javascript-devel] Bug#1101456: fails to upgrade

[VA]

Package: javascript-common
Version: 12
Severity: serious

For some reason, javascript-common fails to upgrade, and it also fails 
to be reinstalled, which prevents from upgrading dependents.

```
# dpkg --configure --pending
Setting up javascript-common (12) ...
dpkg: error processing package javascript-common (--configure):
  installed javascript-common package post-installation script 
subprocess returned error exit status 1
dpkg: dependency problems prevent configuration of dokuwiki:
  dokuwiki depends on javascript-common; however:
   Package javascript-common is not configured yet.

dpkg: error processing package dokuwiki (--configure):
  dependency problems - leaving unconfigured
Errors were encountered while processing:
  javascript-common
  dokuwiki
```

I tried to follow what's inside #718318 but I have no javascript-common 
file in /etc/apache2. I don't have lighthttpd, so I removed 
/etc/lighttpd (which contained files from javascript-common, see 
#912002) and tried to install again:

```
# dpkg -i javascript-common_12_all.deb
(Reading database ... 482559 files and directories currently installed.)
Preparing to unpack javascript-common_12_all.deb ...
Unpacking javascript-common (12) over (12) ...
Setting up javascript-common (12) ...
javascript-alias was disabled in lighttpd.
Hint: Use "lighttpd-enable-mod javascript-alias" to re-enable.
dpkg: error processing package javascript-common (--install):
  installed javascript-common package post-installation script 
subprocess returned error exit status 1
Errors were encountered while processing:
  javascript-common
```

As you can see, there's no error message indicating why it fails.
