With the snapshots build from 2010-11-11-02-36 KMail does not start on Windows CE, all other frontends do start. Output is: Data Abort: Thread=8a7822d0 Proc=80462280 'kmail-mobile.exe' AKY=00400001 PC=662779b0(???+0x662779b0) RA=792760a8(qtcore4.dll+0x000160a8) BVA=2e000000 FSR=00000007 Unhandled exception at 0x662779b0 in kmail-mobile.exe: 0xC0000005: Zugriffsverletzung beim Lesen an Position 0x00000000.
Workaround added in r1195605.
"Clean fixes are better than workarounds." But with version 4.6 svn 1204839 kmail-mobile starts and doesn't crash anymore. So I close this issue.
This bug was investigated and caused by an encoding error in kdelibs for WinCE which has since then been fixed so a clean fix is there but was not added to the bugreport. r1197394
