In a document of mine I'm trying to use the external library. For the record, I downloaded the CVS version of TikZ, since I want the better update checks. Anyway, I have a figure in my code which compiles perfectly as long as I have \tikzset{external/export next=false} in front of it; that is, the figure's code is correct. However, once I change the value to true, then I get the following error (I hope this is indeed the relevant part):
(./figures/region-bounded-by-hyperbolas.tex
Runaway argument?
{ \clip (-3,-2) rectangle (4,3); \draw [thick,gray,->] (-2.5,0) -- (3\ETC.
./figures/region-bounded-by-hyperbolas.tex:83: Paragraph ended before \tikzexternal@externalizefig@systemcall@uptodatecheck was complete.

\par

./figures/region-bounded-by-hyperbolas.tex:83: ==> Fatal error occurred, no output PDF file produced!
When using the 2.10 version this seems to work fine for both boolean values - unfortunately then the update method is poor.
Is this a bug? Am I doing something wrong? How can I debug/troubleshoot this?
Edit 1: I just installed an even newer version of TikZ, 4.8.2012 (following the suggestion here), and everything seems to work as expected. Thus, it seems like the issue I experienced was a bug. In case no further insights are provided, then I'll flag to close this questions
