Package: akregator
Version: 4:4.3.2-1
Severity: important
--- Please enter the report below this line. ---
Akregator freezes for around 5 seconds and does not respond at all.
This happens every half a minute, but it is random. It does not seem to be
related with a given
action. This bug makes the use of it very annoying.
I have around 150 sources with 5000 messages in total. I have attached gdb to
it when it freezes and produced
two stack traces that I attach. I have also profiled akregator with oprofile to
show the functions that hog the CPU.
This are the first lines output from opreport -a --symbols -m all:
