Just found out that there is some very dangerous UK supplied quickmatch doing the rounds. The powder coating on the internal string is very fine and light grey in colour and not black courser powder as is usually the case. This stuff is dangerous and will ignite with the slightest of friction, so if anyone has any, don't use it. Return it back to the source if possible, or chuck it all in a bucket of water.
edit - sorry Pete, forgot about the fuse forum. Thanks for moving it.
