Ubuntu 12: java crashed with SIGABRT in tesseract::Classify::CharNormClassifier() --- Tesseract 3.0 language files missing?

[Mike Williamson]

Tried to run a siklui script after installing the package sikuli-ide. After the crash my home directory was fully of many versions of an image that it looks like sikuli was in the middle of dissecting when it died.

mike@sleepycat:~$ sikuli-ide

Thank you for your report!

However, processing it in order to get sufficient information for the
developers failed (it does not generate a useful symbolic stack trace). This
might be caused by some outdated packages which were installed on your system
at the time of the report:

outdated debug symbol package for libv4l-0: package version 0.8.6-1ubuntu1 dbgsym version 0.8.5-3ubuntu2

Please upgrade your system to the latest package versions. If you still
encounter the crash, please file a new report.

Thank you for your understanding, and sorry for the inconvenience!

Ubuntu 12.04 seems to have Tesseract 3.0 installed.
As the Tesseract docs say, you have to install the language support packages your self, they are no longer contained in the software distro (as with Tesseract 2.0).

So this might be an Ubuntu packaging problem.
