GIMP version at least 2.2.7 (haven't found earlier versions to try) and above (including latest 2.2.13) has a bug that makes it crash when the LANG environment variable is set to some languages that use "long" strings (I think). The Russian language I use (LANG=ru_RU) uses 2 bytes per character in UTF-8; it looks like the randomizer plugin uses somewhere a static buffer for NLS strings which gets overwritten if the strings are too long.

To reproduce, run:

[zap@zap]LANG=ru_RU gimp

After that choose File->New (Файл->Новый), create a default canvas, then choose Filters->Noise->Hurl / Pick (Фильтры->Шум->Бросок / Выбор), then press OK. A message box telling that the plugin has died unexpectedly will pop up. In the console you will see the following message:

*** buffer overflow detected ***: /usr/lib/gimp/2.0/plug-ins/randomize terminated
======= Backtrace: =========
/lib/libc.so.6(__chk_fail+0x41)[0x6232b1]

This should work with glibc 2.4 and above which have a built-in memory trashing detector. With earlier glibc's the bug could not manifest instantly but neverless trashing memory is not a good thing in any case.
