--- Comment #6 from Christoph Vogtländer <k...@mockies.de> --- I launched my favorite debugger and found the problem: mainwindow.cpp:1006: QLatin1String fsName = QLatin1String(rePartition.captured(4).toLatin1()); >From the Qt documentation: QLatin1String::QLatin1String(const QByteArray &str) Constructs a QLatin1String object that stores str. **The string data is not copied. The caller must be able to guarantee that str will not be deleted or modified as long as the QLatin1String object exists.** So it is a mistake to construct a QLatin1String from a temporary. As "fsType" is required to be a QString later anyway, a possible fix would be to simply create a QString: QString fsName = rePartition.captured(4); I tested this and it works. But, this has explicitly changed in 4b4198c34a9f4880546242de330138cc11da8359 together with the creation of "fs*". The latter was reverted in 24237a6120e31f1051a07499f04c7391b877552c -- You are receiving this mail because: You are watching all bug changes.
