Instant crash when loading plugin

[Fritz Sicher]

After update from raring to saucy I instantly get a crash upon trying to load the OTR plugin:

[(status)] /load otr
Program received signal SIGSEGV, Segmentation fault.

For debugging symbols I had to build irssi myself, but no changes to the source were done. Due to compatibility issues (some required other packages require perl 5.14) I'm running Perl 5.14 instead of the more recent 5.18 release (wich shouldn't matter here too much).

Possibly affected packages are:
irssi:
  Installiert: 0.8.15-5ubuntu2
  Installationskandidat: 0.8.15-5ubuntu2
  Versionstabelle:
 *** 0.8.15-5ubuntu2 0
        500 http://de.archive.ubuntu.com/ubuntu/ saucy/main amd64 Packages
        100 /var/lib/dpkg/status
irssi-plugin-otr:
  Installiert: 1.0.0~alpha2-1
  Installationskandidat: 1.0.0~alpha2-1
  Versionstabelle:
 *** 1.0.0~alpha2-1 0
        500 http://de.archive.ubuntu.com/ubuntu/ saucy/universe amd64 Packages
        100 /var/lib/dpkg/status

I have this issue with multiple computers with different configuration. Currently can't have a look at the other computer's configuration though.

Status changed to 'Confirmed' because the bug affects multiple users.
