[Bug 58175] Re: Kate hangs on spellcheck

[Tom S.]

Please ignore my spurious strace interpretation: with kdelibs-dbg and a
debugging build of kate, I've stepped through
KateSpell::spellcheck(const KateTextCursor &from, const KateTextCursor
&to) in kdelibs-3.5.2/kate/part/katespell.cpp (line 86) past the
assignment to KSpellConfig *ksc (line 109) and until the assignment to
int enc (line 116).

An empty string is returned by m_view->doc()->encoding() with the result
that enc is -1. The next kdDebug message (line 120) accesses
ksEncodings[enc] and Qt complains that -1 (or i = 18446744073709551615
as it reports) is out of range.

At least that's how it seems to me - I'm afraid I wasn't able to patch
kdelibs to confirm this (compilation fails with a missing
remoteservice.moc... I guess I must be doing something wrong)! :o|

Anyway, at least this further debugging has identified a work-around: to
explicitly set the encoding via "Tools > Encoding" (reselecting "Unicode
(utf8)" does the trick) before invoking a spellcheck. Interestingly, it
doesn't appear to matter whether "Settings > Configure Kate > Editor >
Open/Save > File Format > Encoding" is "KDE Default" or "Unicode
(utf8)".
