My distro forced me to update to 1.0.2rc2 (was at 0.9.3). After this I started to notice that on ctrl+v single letters is being inserted. However I am sure that I did not copy them (it does not have any sence). But I notice also that those single letters are part of the phrase/string I copied before.
I do not know how this can happen, but I noticed this more than just couple of times.
