This only seems to be a problem on devices with a mix of Mir 0.6 and 0.7. If you flash devel-proposed for example you'll get pure Mir 0.7.0 and no problem.
If the problem is indeed just that we failed to bump MIRCOMMON_ABI then that's understandable. In fact I did bump it and the change got reverted because there wasn't strong evidence of it actually being necessary. Needs more investigation, although it would be relatively harmless to just bump MIRCOMMON_ABI on development-branch right now. ** Description changed: I'm getting: unity-system-compositor: symbol lookup error: /usr/lib/arm-linux- gnueabihf/libmirserver.so.24: undefined symbol: _ZTIN7android7RefBaseE $ system-image-cli -i current build number: 13 device name: krillin channel: ubuntu-touch/ubuntu-rtm/14.09-proposed last update: 2014-09-03 07:58:22 version version: 13 version ubuntu: 20140903 version device: 20140902-42bae3c Installing unity8-autopilot from a silo pulled in libmircommon1 (see attached excerpt from apt history.log), but I'm left with a mix of Mir 0.6.1 and 0.7.0: $ LANG=C apt-cache policy libmirserver24 libmircommon1 libmirclient8 libmirserver24: Installed: 0.6.1+14.10.20140814-0ubuntu1 Candidate: 0.6.1+14.10.20140814-0ubuntu1 Version table: *** 0.6.1+14.10.20140814-0ubuntu1 0 500 http://derived.archive.canonical.com/ubuntu-rtm/ 14.09/main armhf Packages 100 /var/lib/dpkg/status libmircommon1: Installed: 0.7.0+14.10.20140829~rtm-0ubuntu1 Candidate: 0.7.0+14.10.20140829~rtm-0ubuntu1 Version table: *** 0.7.0+14.10.20140829~rtm-0ubuntu1 0 500 http://derived.archive.canonical.com/ubuntu-rtm/ 14.09/main armhf Packages 100 /var/lib/dpkg/status libmirclient8: Installed: 0.6.1+14.10.20140814-0ubuntu1 Candidate: 0.7.0+14.10.20140829~rtm-0ubuntu1 Version table: 0.7.0+14.10.20140829~rtm-0ubuntu1 0 500 http://derived.archive.canonical.com/ubuntu-rtm/ 14.09/main armhf Packages *** 0.6.1+14.10.20140814-0ubuntu1 0 100 /var/lib/dpkg/status ProblemType: Bug DistroRelease: Ubuntu RTM 14.09 Package: libmircommon1 0.7.0+14.10.20140829~rtm-0ubuntu1 Uname: Linux 3.4.67 armv7l ApportVersion: 2.14.7-0ubuntu1 Architecture: armhf Date: Wed Sep 3 10:33:53 2014 InstallationDate: Installed on 2014-09-03 (0 days ago) InstallationMedia: Ubuntu Utopic Unicorn (development branch) - armhf (20140903-030204) SourcePackage: mir UpgradeStatus: No upgrade log present (probably fresh install) ------ - The package that was upgraded pulled in a new version of qtdeclarative5-qtmir-plugin which pulled in the new version of mircommon1 but not the current version of mirserver.
