So it seems that several 3DS owners such as Taku in another thread have been getting this error with the 3DS.
On the plus side, it's good to see them acknowledge the issue at least.
Nintendo has now commented on the issue to Eurogamer. They apparently recommend upgrading your firmware and then contacting them if that doesn't fix the issue.taku said:
BLARGH! Does this mean I have to get it replaced? How about all my saves? How about my friend code? Damn it!

Nintendo has acknowledged the widely-reported 3DS bug that crashes the device and recommended that anyone experiencing it makes sure they download the latest system update.
"If anyone is experiencing any problems with their Nintendo 3DS console, we recommend that in the first instance they download and install the latest system update, now available online," read a Nintendo statement handed to Eurogamer.
"If the problems still persist we recommend they contact their local Nintendo Customer Service centre to investigate the problem further."
Reports started circulating soon after launch this weekend that many 3DSes were crashing, bringing up a black screen suggesting the owner reboot the system or get in touch with customer services should the problem persist.
On the plus side, it's good to see them acknowledge the issue at least.
