Package: graphviz Version: 2.40.1-2 Severity: normal On recently upgrading packages, I had graphviz 2.40.1-2 but libgvc6 2.38.0-18. This combination caused "dot" to segv when asked for -Tsvg or -Tpng output (and was ok on getting the corresponding 2.40 library).
I got to that combination just by apt-get install graphviz upgrading from what had been 2.38. Perhaps graphviz package could have a versioned dependency of libgvc6 to be sure of bringing in what it needs. -- System Information: Debian Release: buster/sid Architecture: i386 (i686) Versions of packages graphviz depends on: ii libann0 1.1.2+doc-6 ii libc6 2.27-3 ii libcairo2 1.15.10-1 ii libcdt5 2.40.1-2 ii libcgraph6 2.40.1-2 ii libexpat1 2.2.5-3 ii libgcc1 1:8-20180218-1 ii libgd3 2.2.5-4 ii libglib2.0-0 2.56.0-4 ii libgts-0.7-5 0.7.6+darcs121130-4 ii libgvc6 2.40.1-2 ii libgvpr2 2.40.1-2 ii libice6 2:1.0.9-2 ii liblab-gamut1 2.40.1-2 ii libltdl7 2.4.6-2 ii libpango-1.0-0 1.42.0-1 ii libpangocairo-1.0-0 1.42.0-1 ii libpathplan4 2.40.1-2 ii libsm6 2:1.2.2-1+b3 ii libstdc++6 8-20180218-1 ii libx11-6 2:1.6.4-3 ii libxaw7 2:1.0.13-1+b2 ii libxdot4 2.38.0-18 ii libxext6 2:1.3.3-1+b2 ii libxmu6 2:1.1.2-2 ii libxpm4 1:3.5.12-1 ii libxt6 1:1.1.5-1 ii zlib1g 1:1.2.8.dfsg-5 Versions of packages graphviz recommends: pn fonts-liberation <none> Versions of packages graphviz suggests: ii graphviz-doc 2.40.1-2 ii gsfonts 1:8.11+urwcyr1.0.7~pre44-4.4 -- no debconf information
