Bug#911502: calligra FTBFS 'memCheck' is not a member of 'Object'

[peter green <plugwash@p10link.net>]

Package: calligra
Version: 1:3.1.0+dfsg-3
Severity: serious.

During the rebuild for the poppler transition calligra failed to build with

> /<<BUILDDIR>>/calligra-3.1.0+dfsg/filters/karbon/pdf/PdfImport.cpp: In member function 'virtual KoFilter::ConversionStatus PdfImport::convert(const QByteArray&, const QByteArray&)':
> /<<BUILDDIR>>/calligra-3.1.0+dfsg/filters/karbon/pdf/PdfImport.cpp:106:13: error: 'memCheck' is not a member of 'Object'
>       Object::memCheck(stderr);

Since this is in a pdf related file I presume the new poppler was the cause of the build failure.
