I think that may have a lot to do with it. I recall several threads in the general area in the past with complaints about fires being attributed to electrical causes without any clear evidence of such.
Oh yeah... the best wording in a fire report that I remember was: "The cause of the fire could not be determined as the building was not wired for electricity!"
In Austria only one of the big devastating fires in the last few years was blamed on electrical faults, namely old cloth covered wires arcing and setting the old cardboard Bergmann conduit on fire. The others I remember were caused by construction workers being careless with a blow torch.
