I noticed this strange and very annoying behavior - is it possible to tweak it?

Yes, of course it is.
React with dbus-settings to the end of call and reset lower limit to 250/500.
But it is not needed as this frequency is blocked in kernel settings and therefore not taken into account. Speaking about kernel-power.

i will use dbus if i'll have no other choice, but i'm looking for a "cleaner" solution

This should do it, however AFAIK it should be blocked by default.Code:echo 125000 > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/avoid_frequencies
But as it is blocked, your min freq will still be 250 MHz. For that, the new min. value of 125 MHz is bogus.
Code:
cat /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state

The only time I've seen anything do this was in early versions of speedpatch. If you're running and older version of that, do update it (or remove it). 125Mhz is unstable, and doesn't allow transition fast enough to handle all cases (missed calls, etc) which is why Nokia avoided using it in the first place.
Personally, I run 0/500/900 with a large step threshold and have no issues with low battery or lack in usability.

"Correct Frequencies" can all depend on usage and the device, it's been covered lots of times before.
While I wouldn't recommend it to all, after long periods of testing different frequencies with my device and usage. I run 125-600 and have no issues with low battery or lack in usability. I have never experienced any issue with 125Mhz being unstable.
Bear in mind that since the "125Mhz unstable issue" was reported, smartreflex has been fixed and also there have been new releases of KP.
For reference this is the bugzilla link:-

if no other choice, i guess i'll be executing my kernel power command to set a profile after each call end with dbus...
