A short list, some minor SPOILERS:
Started the campaign, everything went fine up until I got my first city. When I was in build mode the first time, the view did zoom out again, but stayed in the same angle as in build mode, that means watching straight down. Might have been produced by me accidentally moving my mouse wheel a notch while in build mode. Still, I continued to play. Screen on world map (and cloth map) stayed in that position.
Second problem - during the fight with the bigger spider I gave my units orders for more than one turn. The spider strayed into the path of one unit, which promptly (before I could intervene) stepped into the same square as the spider. Hilarity ensued - I could not attack, the spider killed two of my units, then a turn later the blocking unit left the spiders square. My channeler then killed the spider.
Third bug - attacking the darkling village my whole remaining army (including the channeler) was killed, with the main darkling still untouched. The game responded by giving me the 'channeler fled home' message. Then a quest screen appeared, congratulating me on my success and pointing out more Darklings in another place to the south. Seems to be so stupid and not be able to kill the Darklings was not thought of.
Then I quit and started a skirmish. In the first turn I got a huge 'out of memory' message in front of a black screen and the game just hung. Alt-tabbing out of there after two minutes led to a Dx-something error. There is no zip (as asked for in the crash report advice), but the debug.err is here:
