kdepim plugin generates spurious QFile::writeBlock error

[Graham Cobb]

Whenever I perform a synchronisation which includes kdepim I see the following error logged in the output a couple of times near the end:

QFile::writeBlock: Write operation not permitted

The error seems to cause no problem -- the entries seem to be written -- but it is confusing for new users, particularly if they are trying to track down a problem.

I have just realised what may be causing this. In my Kontact setup I have several calendar resources and several contacts resources. Of these, most are marked read-only.

I get these errors reported for every attempt to modify an entry in the read-only resources, which is not unreasonable (although a more meaningful error would be good -- maybe kdepim could check if the resource is read-only before attempting the update?).

However, I also get two of these errors even when the synchronisation involves no updates to entries in these resources (or, indeed, any changes at all on the kdepim side). Maybe kdepim-plugin is doing some sort of update to the resource even when nothing has changed?

The message is confusing and shows a problem (because libkabc is trying to do the wrong thing). But this has no problems other than showing that message, fortunately.

The problem was fixed on KDE svn. See ​commit and ​related ticket.
