Package: calibre Version: 3.23.0+dfsg-1 Severity: minor Dear Maintainer,
I open any ebook in calibre viewer. Table of Content panel is open. Then I switch to another gnome workspace and back. Table of Content panel gets closed. I have to reopen it with Ctrl-T (or icon). The same error in calibre 2.75 in stable (stretch). -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.15.0-3-amd64 (SMP w/2 CPU cores) Locale: LANG=pl_PL.UTF-8, LC_CTYPE=pl_PL.UTF-8 (charmap=UTF-8), LANGUAGE=pl_PL.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages calibre depends on: ii calibre-bin 3.23.0+dfsg-1 ii fonts-liberation 1:1.07.4-6 ii imagemagick 8:6.9.9.34+dfsg-3+b1 ii imagemagick-6.q16 [imagemagick] 8:6.9.9.34+dfsg-3+b1 ii libjs-coffeescript 1.12.7~dfsg-3 ii libjs-mathjax 2.7.3+dfsg-1 ii poppler-utils 0.63.0-2 ii python-apsw 3.16.2-r1-2+b1 ii python-chardet 3.0.4-1 ii python-cherrypy3 8.9.1-2 ii python-cssselect 1.0.3-1 ii python-cssutils 1.0.2-1 ii python-dateutil 2.6.1-1 ii python-dbus 1.2.6-1 ii python-feedparser 5.2.1-1 ii python-html5-parser 0.4.4-1 ii python-lxml 4.2.1-1 ii python-markdown 2.6.9-1 ii python-mechanize 1:0.2.5-3 ii python-msgpack 0.5.6-1 ii python-netifaces 0.10.4-1 ii python-pil 4.3.0-2 ii python-pkg-resources 39.1.0-1 ii python-pyparsing 2.2.0+dfsg1-2 ii python-pyqt5 5.10.1+dfsg-1 ii python-pyqt5.qtsvg 5.10.1+dfsg-1 ii python-pyqt5.qtwebkit 5.10.1+dfsg-1 ii python-regex 0.1.20171212-2 ii python-routes 2.4.1-1 ii python2.7 2.7.15-1 ii xdg-utils 1.1.2-2 Versions of packages calibre recommends: ii python-dnspython 1.15.0-1 calibre suggests no packages. -- no debconf information
