I've got a small webkit2gtk-based browser which uses:

webkit_web_context_set_spell_checking_enabled(c, true);
webkit_web_context_set_spell_checking_languages(c, lang);

After updating webkit2gtk to 2.18.3-3 and enchant to 2.1.2-1 (both from [testing]) I get the following segfault:


(gdb) run

Same after rebuilding squaw against the new libraries. However all is well if I remove those two lines above from the source C file that enable spell_checking... Here's the source if it matters: https://fenua.org/gaetan/src/squaw-3.1.c

But I do not believe it does. Is there any webkit2gtk-based browser that enables enchant and does not segfault with the new libs?

Cheers.
This task depends upon

The enchant voikko backend dereferences a NULL pointer when voikko supports no languages.
