That is a bug that was fixed recently:

Yes, I have done that. On GDB I set some breakpoints.

Breakpoint 2, marshall_ItemList<Okular::Page, QVector<Okular::Page*>,
((const char*)((char*)(&<unnamed>::OkularPageListSTR)))>
(m=0x7fff49955350)
    at /home/kde/src/KDE/kdebindings/ruby/qtruby/src/marshall_macros.h:131
131                               int count = RARRAY_LEN(av);
(gdb) c
Continuing.

Breakpoint 4, marshall_ItemList<Okular::Page, QVector<Okular::Page*>,
((const char*)((char*)(&<unnamed>::OkularPageListSTR)))>
(m=0x7fff49955350)
    at /home/kde/src/KDE/kdebindings/ruby/qtruby/src/marshall_macros.h:133
133                               cpplist->clear();
(gdb) p count
$2 = 0

As you can see, RARRAY_LEN reports a 0 elements.
