Externals: sqlite: constraint failed

Hi,

I'm momentarily getting strange errors handling some externals,
like (on 'svn up'):

---
Fetching external item into 'module/tags/BUILD_module_V1.0.0/ant-scripts':
External at revision 122958.
svn: warning: W200000: Error handling externals definition for 'module/tags/BUILD_module_V1.0.0/ant-scripts':
svn: warning: W200035: sqlite: constraint failed
----
Lots of that (for a lot of externals), ending expectedly with
----
At revision 122958.
svn: E205011: Failure occurred processing one or more externals definitions
----
No other special occurrences; previous operations on that WC were
unproblematic. (This *may* have to do with a 'svn relocate' operation
on the WC, but URLs look ok.) It is a checkout of a tree containing a ot
of modules with trunk/tags/branches so there are many externals in the WC
(a few for each module trunk/tag).
