Yes, it's definitely some problem with MicroB engine. Question is, what kind of problem? Re-installing microb-eal (yes, it is available on maemo.org directly; though, it might need maemo5.0 distribution) did not seem to fix it.

/And yes, nokia.com repositories being down, and apt-get complaints about it, were pretty much ignored by me, all this time... Heard, but not thought about/

Where do I get strace package from? I do not see it in apt-get... /Of course, I can go Debian-hunting for armel-compiled version of the package, like I did with xpaint.../

Reinstalling browser-eal, just in case. And reading /etc/ld.so.conf...

Thank you. Best wishes.

[Edit]
There were only two microb lines. So I am prepending the other lines

/usr/X11R6/lib
/usr/local/xrdp
/usr/local/lib
/usr/lib
/lib
/usr/lib/microb-engine
/usr/lib/microb-engine/components

to see what it gives.

Exactly same errors
