sikuli ide does not start

When I start sikuli-ide, no window appears, nothing happens.

Here is my log from console:

$ sikuli-ide -s
[info] locale: ru_RU
$

`sikuli-ide -h` gives me a valid sikuli help, though.

My sikuli-ide is the package from the repos, modified as suggested here: #1313398 ( https://bugs.launchpad.net/ubuntu/+source/sikuli/+bug/1313398 )
