Subject: fuzzyocr: Warnings while scanning PDFs Package: fuzzyocr Version: 3.6.0-3 Severity: normal
*** Please type your report below this line *** Occasionally I receive an email with PDF attachment that causes SpamAssassin to spew out the following Perl warnings: spamd: Use of uninitialized value $file in concatenation (.) or string at /usr/share/perl5/FuzzyOcr.pm line 382. spamd: Use of uninitialized value $file in concatenation (.) or string at /usr/share/perl5/FuzzyOcr.pm line 383. spamd: Use of uninitialized value $mimetype in pattern match (m//) at /usr/share/perl5/FuzzyOcr.pm line 396. spamd: Use of uninitialized value in pattern match (m//) at /usr/share/perl5/FuzzyOcr.pm line 400. spamd: Use of uninitialized value $mimetype in concatenation (.) or string at /usr/share/perl5/FuzzyOcr.pm line 406. spamd: Use of uninitialized value in concatenation (.) or string at /usr/share/perl5/FuzzyOcr.pm line 722. spamd: FuzzyOcr: Cannot exec pdftops, skipping image spamd: FuzzyOcr: Cannot exec pstopnm, skipping image spamd: FuzzyOcr: Cannot exec pdfinfo, skipping image I have discused this with upstream and the fix is in the main FuzzyOCR.pm code, adding a missing hash member 'delete' statement when skipping PDF types, just like what happens with all the other skipped types. Attached is a one-liner patch.
