 Well, I know this general rule, and that's why I asked. If I don't backport 
anything, we get even more reports with useless info. If I backport only the 
fixes, we will get bugreports even without it, just with complaints that 
drkonqi doesn't let them save the backtrace and that they don't know what to 
do. No big difference. Ok, we now have a bugsquad, but I still don't see why 
not help them a little.

 Does it? Where?

 It normally analyzes the output from gdb and guesses from the backtrace. See 
BackTraceGdb::checkUsefulBacktrace().

 It is not the distro who usually gets the report though, and the distro also 
doesn't know where in the backtrace a library is needed.

 That backtrace is currently not considered to be good enough, regardless of 
the irrelevant thread 1, but I take this that it should be strict only with 
really broken backtraces.
