I did ran into the same assertion error with changeset 33655 in my windows repository, but not in the Linux build system.
In file
'D:\Development\SVN\Releases\TortoiseSVN-1.7.9\ext\subversion\subversionlibsvn_wc\update_editor.c'
line 1583: assertion failed (action == svn_wc_conflict_action_edit || action
== svn_wc_conflict_action_delete || action == svn_wc_conflict_action_replace)
I reported the error also to TortoiseSVN bug tracker, but got feedback that the error is related to the main subversion libraries, not just the TortoiseSVN GUI. (http://tortoisesvn.tigris.org/ds/viewMe … Id=3018909)
That changeset r33655 contains in addition to normal changes for bcm_tag.h also a removal of a "special property": https://dev.openwrt.org/changeset/33655
After several cleanup/resolve/delete etc. attempts I got my repository straightened up.
