[CLucene-dev] Indexing fails with .. FIELDS_INDEX_EXTENSION).c_str() )' failed

[Akash <akb...@gm...>]

Hi,

I am using Dovecot with its clucene plugin for indexing. I am hitting a 
error while trying to index a large folder of emails. Sometimes it 
throws this error after 30000 emails, sometimes 40000, the latest it 
gave up after 111000. But it just never completes. On Dovecot list, I 
was told that its probably CLucene library bug which they can't do much 
about & I was suggested to switch to solr (which I don't want to). Can 
there be a fix for this:

111000/322080 doveadm:
/home/stephan/packages/wheezy/i386/clucene-core-2.3.3.4/src/core/CLucene/index/DocumentsWriter.cpp:210:
std:tring lucene::index:ocumentsWriter::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.
