Randomly got this error upon logging in:
1x ...ceArchy\Libs\LibDialog-1.0\LibDialog-1.0-5.lua:899: attempt to index local 'delegate' (a nil value) ...ceArchy\Libs\LibDialog-1.0\LibDialog-1.0-5.lua:899: in function `Resize' ...ceArchy\Libs\LibDialog-1.0\LibDialog-1.0-5.lua:974: in function <...ceArchy\Libs\LibDialog-1.0\LibDialog-1.0.lua:973> (tail call): ?
I've never seen this error before, and wasn't able to reproduce it by reloading the UI, relogging, or restarting the client. At the time of the error, I was on a level 4 shaman, trial account, EU servers, German locale, bunch of other addons enabled, though Archy is the only addon I have using LibDialog-1.0. No dialog was shown, nor did I expect one to be shown.
LibDialog-1.0 minor version is 5, though since that doesn't seem to correspond to a revision number I can't even tell you which revision it is, other than "whatever was packaged with the latest version of Archy".
Feel free to ignore this if you want, but I've done my duty and reported it. :P
