[Nepomuk] How to debug virtuoso crashes?

[Lindsay Mathieson]

Hi Vishesh, some more information I think is relevant. I've verified my
feeder is trimming the text content down to size before submitting it for
indexing. However I'm seeing the following debug output (below).

Whats odd is the nmo#plainTextMessageContent - its the complete untrimmed
text of about 4MB, so its still being submitted somehow.

However the destination url for the insert -
nepomuk:/ctx/1c8fcf90-94f1-428a-b929-fbe0b21977a1, is some Intermediate
destination type (sorry, posting from memory), its not processed via void
setNmoPlainTextContent(const QUrl& uri, const QString& plainText_) - I
can't figure out where its coming from. But the result is that virtuoso
keeps crashing :(
