cl.c@8fb4b0b043c0, line 297:

GList *g = g_list_first(g_hash_table_get_values(mrim->groups));

В список групп каким-то образом попадают элементы с .name != NULL и непригодные для g_strcmp0.

Идеи есть?

Проблема: первый же результат в списке mrim->groups, судя по всему, какой-то мусорный или является не MrimGroup-структурой.

При этом свёрнутая группа не считает этого собеседника состоящим в ней и пребывающим в сети: ИмяГруппы (5/150), когда в группе в сети отображается 6 контактов. Полагаю, это связано.

В mrim.c:141 g_hash_table_destroy(mrim->groups); Таким образом, в mrim->groups есть неожиданное значение.
