Indexing fails with .. FIELDS_INDEX_EXTENSION).c_str() )' failed

[Akash]

Hi,

Mailing list archives suggest that this problem has been fixed in the
older versions itself but I am getting the error still while trying to
doveadm index a large folder of emails. Sometimes it throws error
after 30000, something 40000, the latest it gave up after 111000. But
it just never completes.

111000/322080doveadm:
/home/stephan/packages/wheezy/i386/clucene-core-2.3.3.4/src/core/CLucene/index/DocumentsWriter.cpp:210:
std::string lucene::index::DocumentsWriter::closeDocStore(): Assertion
`numDocsInStore*8 == directory->fileLength( (docStoreSegment + "." +
IndexFileNames::FIELDS_INDEX_EXTENSION).c_str() )' failed.
Aborted

I am using dovecot 2:2.2.19-1~auto+7& libclucene-core1:i386 2.3.3.4-4
from debian wheezy backports. Please advice.
